I reported this in a bug report but figured I would post here to see if others are having this issue.

I have suspected for several weeks that something is off with PPC hit detection(ie: ever since HSR). I haven't had anything concrete to "prove" it other than seeing hits strike visually and having no damage show up in the target damage display. Today I had something close to "concrete" evidence...at least for me.

This is what happened: I had the opportunity to engage a disco near the enemy base on Alpine all by myself in a regular match. I engaged no other mechs that round as I went a different direction than the rest of my team. It was a highlander. I was in a 4 PPC stalker (3F). I purposely aimed for different locations but several times it was clear that my hits registered visually but not in the display. At the end I had 573 damage and 1 kill. Armor on that mech is only 558 max. I didn't destroy everything. These results appear suspect. It is almost like my damage counter is working but the actual damage counter for the mech I am hitting is not. I intend to start FRAPing this phenomena and send it to PGI.

Anyone else having PPC's strike the target but register no damage to the target?

[CutterWolf]

Yes, several of my team mates and I are having this "No damage transfer bug with PPC's" with both PPC's & ERPPC's. We are also trying to get it on FRAP's. I have already sent in a support ticket on the problem but PGI has requested video of it. Also one of my team mates was able to reproduce this in the testing grounds so you mite want to try it there and see if you can get it on FRAP's

[DeaconW]

Thx CutterWolf. I will see if I can demo this in training grounds.

[SixstringSamurai]

I notice it most often when shooting at the Highlander. Several times I've fired almost point blank at a Highlander and gotten nothing. But I've also seen it to a lesser extent on my own mech, getting the impact from a PPC and absolute zero damage from it.

Wonder if there is something about the Highlander that is causing this? I didn't think about it until you said it but given the sheer number of highlanders in matches since it came out, this effect would be more noticeable. I will start trying to see if there is a pattern WRT highlanders. I just did one round in the training grounds but every shot hit.

Send a ticket with your PC Specs if you haven't already (as I understand, some of you have). Was there any lag when firing the PPCs? What was your Ping? Send that info to Support and we'll see what we can do. Thanks for the feedback!

Yes, this would definitely be one of the observable side effects. In fact, it should not be specific to ballistics. If you start experiencing the bug to the extreme as some have described here, you should not be able to hit targets with any kind of weapon.

Seen this yet?

Thx for this...it may be the issue but I wasn't experiencing noticable lag and my ping is typically less than 80.

Thx. I did send a ticket. Haven't been asked for any further info. No lag. My ping is typically less than 80ms. This link looks like a promising reason: http://mwomercs.com/...ost__p__2276860

I payed attention today using a twin PPC and Guass 1X and low and behold, there
were hits that did not reduce the enemies % at all...

Interesting...

[SkkyHigh]

Not sure if this is related but 3 times this morning I've been Rear Center Torso destroyed while facing the enemy.

The PPCs seemed to pass right through my front amour.

[JuiceKeeper]

i noticed this bug also. Currently i dont use ppc`s but i noticed sometimes when i get shot by them hit is not registered. Its definitly noticable even when u spectating some matches. Its more noticable on lights but it also happening on assaults and heavies.

Hey everyone,

We are aware of this issue and are actively working on solving it. This particular problem occurs when you experience regular packet loss--even a very small amount. Primarily the traffic from your game client to the server is affected. This is why you might see other players behaving normally, but your inputs seem to be delayed, you suddenly pop, or a variety of other strangeness.

The problem is not related to HSR or ping. So, why is this happening now? Traffic patterns from recent patches have changed, which have unfortunately exposed this latent bug.

For everyone experiencing this bug, hang in there, a fix is on the way.

[random question about this is why ballistics aren't doing damage on a clear hit]

Hey everyone, I must apologize greatly for this. There has been a lot of work under the hood in preparation for 12v12. Part of those changes have been aggressive bandwidth optimizations so that users don't end up left out due to increased network load when 12v12 is turned on.

Some of these changes actually went live a couple patches ago, and involved sending lots of small little acknowledgements back to the server so that the server could intelligently compress what it sends to your client. Unfortunately, once again we appear to have tripped some unfortunate behaviour in the engine which we are currently trying to track down and correct.

In the interim, I have prepared some emergency changes which are being pushed to testing immediately with the intent to launch a hot fix. QA has good reproduction steps for this issue now, so we should be able to easily catch cases like this in future.

We'll update you all as soon as we have more info about QA testing and hot fix approval.

If you read through that, you will see that it's been an ongoing problem, but it the cause was only recently uncovered since many more people were being affected.

Hotfix incoming "soon"

does have this too with ac20

[Statixstorm]

I have also seen this problem, I see it mostly while piloting my 3L with 1 ER PPC and 1 ML. I get it constantly when dog fighting enemy lights and often when I am harassing a heavier opponent.

In addition I'm not sure if this was a PPC bug, or something else, but I noticed a enemy Awesome chilling behind Kappa on Frozen City, turns out he was AFK, well, I rolled up about 50m behind him and started on his rear torso with my ER PPC, each hit with the PPC was putting the damage on his front CT, not his rear, while my ML was properly damaging his back, this again was at full stop 50m directly behind the awesome, I was able to fully core and destroy his front CT from behind him.

I believe this is a different bug. I see this one when I get hit in my jenner a lot.

The PPC's not registering I see in my Stalkers though.

[The Black Knight]

I've noticed this, on alpine especially. its always at long range for me though, so I assumed the ppcs were out of range and that is why they did no damage. And to clarify this is me getting hit with ppcs, and having cockpit shake from the impact but registering no damage on my paperdoll.

[Stregga]

normal PPC's have a minimum range of about 90 meters, so if you fire at a target at less than that (ie point blank) you will do significantly less damage. ERPPC's dont have this limitation

There was no lag when firing the PPC's and my self and my team mates all have pings under 40. This issue is still going on but I have not been able to get it on FRAPS yet. I'm using only ERPPC's and I see this happen a lot, clean hits but no damage transfer.
