LRMs frequently take a sharp angled flight.

Steps to Reproduce
1. Boot the game.
2. Login to the game.
3. Launch a match.
4. Fire LRMs
5. Observe directionality of LRMs

Questions
Does this occur with any mech or a specific Mech?
Does this occur with any size LRM weapon?
Does this occur at any distance or within a specific range?

[aspect]

I have had this issue, it seemed to be related to losing target lock immediately before firing, which would cause my LRM's to fly off to the side.

same as the above poster

+1 on the first post. It happens when I lose lock immediately before the missles fire.

Also, another possible bug, if the missles lose lock during flight, genereally when the enemy 'mech is destoryed around the half-way point of missle fligh, it "appears" that the LRMs will lock onto a new 'mech and hit them.

Normally I'd be ok with this, but it seems the re-lock is 100% of the time, locking on the nearest FRIENDLY units that were in no way 'close' to the original target.

So to be more specific, I fire 2 racks of LRM15s at a target 800 meters away, the target dies or I lose lock at 400 meters, there's a small chance that a portion of the missles will re-lock on a friendly unit at that 400m mark, veer off at a sharp angle to hit and damage him.

usually happens just as i launch after losing a lock at the same time and the missiles fly out at a 90 degree angle to my mech. couple of times every 5 - 10 matches

[Koniving]

I have not voted because I had a similar but related issue.

My Raven 3-L can alternate targets while the missiles are in the air, this was especially true of my LRM-20 Raven firing from the left-arm Narc launcher, this is not a new but ongoing issue. Once I lost a target, I could highlight a new target and my missiles would rapidly change angle and accelerate toward the new target. This has been tested on and in all cases occured with the LRM-20, LRM-15, and LRM-5. The LRM-10 has not been tested for this. These have been without Artemis.

Before this patch, I could do something similar with my Jenner and Commando. Since, I cannot reproduce these with those two mechs, and no other mech seems to be capable of changing targets while missiles are airborne.

[RoboCyberMummy]

This issue occurs when I lose lock as I'm firing LRMs.

Does this occur with any mech or a specific Mech?
I have observed this issue in the AS7-RS and AS7-K. I do not carry LRMs on other mechs.

Does this occur with any size LRM weapon?
I have only used LRM20s. This issue occurs on the group of missiles fired immediately after losing lock.
For example: Firing an LRM20 from the AS7-RS causes 4 groups of 5 missiles to fire consecutively. If I lose lock between the 2nd and 3rd groups, the 3rd group will fire at an angle of approximately 90 degrees to my right. The 4th group will fire normally and hit wherever my crosshairs were pointed at the time of launch, as expected.

Does this occur at any distance or within a specific range?
Losing lock at short range is rare and I can't be 100% certain this issue occurs within 500m. I believe it does.

[steelblueskies]

have occasionally had this occur both with the previous and now with the current patch as first responder indicated. additionally i have found that occasionally the same thing will occur simply by having a target selected("r") in my forward view arc while attempting to "fire for effect" at reticule location (which is any place other than where the selected mech is.

furthermore with a beagle active probe installed, i have seen the same occur while attempting to fire for effect with not target selected with "r" merely a red indicator of an enemy in that general direction, even while firing someplace far removed from target indicator.(have also seen it try to start locking a triangle target indicator without actually selecting the target just by grazing reticule nearby, may be related in some way.)

i can only attest observing this with three atlases(as7-d, as7-d-dc, as7-rs) presently, as that's what i have in my hangars that bear missile hardpoints.

have only tested in recent times while using lrm15, lrm20, and the artemis equipped versions of same.

appears range irrelevant, but easiest to reproduce by losing lock mid fire while moving and having turned from the facing one was at when missile launch began ie by torso twist, with the odd trajectory rounds favoring sharply angled flight at roughly a right angle to the front face plane of your mech, and towards the side closest to prior facing.

and the ">" represent missile flight path from the mechs tubes.

[Thrak]

I've seen this being used to drop missiles behind rocks then have them fly sideways into enemy mechs - at one point I saw missiles heading towards ground then almost head UP to hit a nearby mech very rapidly.

[steelblueskies]

thrak, what you saw was firing with a lock in the open, then target occludes but lock on still possible due to secondary spotter, so the pilot breaks lock to keep missiles firing straight line, then reaquires lock when they have progressed beyond the obstacles(because they reacquire limited tracking capability). while that could be a bug, given they can't pull a perfect right angle or fly back towards the direction they flew in from, i was under the impression that was a skill based mechanic, and is still seemingly a different issue entirely. those can be avoided by moving behind cover and towards the thing firing the missiles 98% of the time( with the 2% involving pyramidal shaped cover and reacquiring the lock while missiles are over part of the cover object, this still loses missiles to the cover however as they try to drop down but are angle restricted both by flight angle and the angle of the cover ).

that was superior to the losing lock and they fall out of the sky, which also made non lock-on missile fire simply fall out of the sky instead of firing to target area under reticle.
--------------------------------------------------------

one other thing. has anyone seeing these things also seen a missile simply exit the tubes flying sideways? i mean sometimes one missile exits the tube flying normally but is drawn side on it's whole flight?

ie instead of seeing the rear "O" you see ">>==>" flying off from you and staying that way?

Same.

[Radosvet]

Lock-on, fire, lose lock, restore lock on same target when missiles very close or even above the target will lead to the abnormal behavior => missiles will hit target always(even fast moving janner), there path will be down to the level of the mech, and then, nearly at the right angle, straight line to the target (they can fly in parallel to the ground)

lock resume

Since this lot of changes in LRM started with 6.November flightpath of LRM is still a bit strange.
Simply roll back to the parameters of flightpath from 5.November and all is fine.
