Out of interest, as I'd love to help where I can with this bug.
What do you guys need? It happens infrequently and I've played long enough to encounter it many, many times to be fairly certain it cannot be reproduced consistently by your players in a live environment.
Not specific to a map, a faction, a point in the game, a class, a weapon etc
Have you been able to repro it in test at all? Do you need more videos? If so where shall we send them? I've sent a vid before but no idea if it got seen or helped.
Im sure many in the community would love to help but are unsure how to. As since you're asking these questions here it seems T17's QA team is struggling to repro this consistently (or at all maybe?)
So yeh bitch to fix I'm sure - what can we do to help? :)
