When choosing your 4 mechs it sometimes resets them before you are done choosing all of them. I found that if save after choosing each one that I had no problems.
On one of my drops I chose a different mech to drop first with, but I found that it still went with the mech on the far left of the list as the 1st to drop with. (I've been putting the one I want 1st on the far left since then.)
And after changing my last mech (the right most in the list of 4) the game used the mech I had there before. After the match it still showed the mech I changed it to. It worked fine in the following matches.
All in all, I still like the new CW. And can see where it will be much better after all the upcoming tweaks and fixes...looking forward to it. (It is in Beta after all.)
