Trenches that are glitched, and people getting stuck into them..
This bug is on the dev list. It seems props randomly disappear. They work on it!
I had no experience of a crash yet (I played at the high peak of the release). Just sometimes I tried to log on a server, it said "Connection to server lost". I think that was more a server problem than a mod problem. I will check out that later again.
Sound bug when rain is allready known.
It seems when using a chauchat LMG and try to make permanent fire, it won't work. The ingame char is just sometimes between the fire "wavering" the LMG instead of constantly "aiming" with it. So a constant, steady fire is not possible (I hold my left mouse button of course).
Second in my opinion LMG classes have too few round strips. In public play you're very fast out of ammo and nobody cares. Should be fixed.
Next is the sniper rifle. It is still too OP in the moment. Aiming is too easy with it. Snipers on the map are everytime on top of the leaderboard. He is better in repelling an assault than a MG is. Should be fixed. Some suggestions:
In my opinion remove the small dot in the middle of the crosshair. For other classes on range accuracy doesn't play any role, but for sniper does. I would prefer a small circle without cross and/or dot.
Maybe the scope should "shake" after every fire, so constant kill combos should be prevented. You need to make him aim again.
