This is a duplicate of an in-game bug report. I cannot offer steps to reproduce yet, here's what I did in the session (at least what could be related to the bug): - I logged in (PTS), I was in the market area under the Senate plaza on Coruscant - I sent my companion off to craft a barrel (armstech) - I accepted an additional mission on the Senate plaza - I used a taxi to travel to the Black Sun sector - While I was in flight, the companion returned from the crafting job - After arrival in the Black Sun sector, I reengineered the barrel - I picked up another mission - I went off to kill some Black Sun people - at some point I noticed that when I wasn't moving for a second or two, the weapon on the back of my companion started flickering at a frequency of ~5 Hz, then I noticed it was rendered alternately on my avatar's back and on the back of my companion. When it was rendered on my back, it was rendered in addition to the weapon I was already wearing (its parts were sticking out of my gun). I have made screenshots showing the weapon alternately on my companions and my avatar's back; if you want them, let me know where to put them. - Whenever I moved or fought, everything was fine. When I stopped moving, the weapon started flickering again after a second or two. - When I tried to unequip the weapon (C window, click on "Companion" tab, right-click on weapon slot), the swtor client crashed to the desktop [after relogging, the weapon was in the inventory, so unequipping worked server-side, but the client ended up in an unexpected state] I will update this post if I find steps to reproduce the problem. Update: didn't find a way to reproduce, I kinda hope the client automagically sent some kind of crash dump to BW. Would be a shame if this turned out to be a real issue after deployment to the live servers.
