I'm going to copy and paste an email I sent to a Bohemia representative concerning issues I've found.
There are a few issues with the game I'd like to report.
There is an ongoing issue where the game will crash in the pregame lobby. I recently lost two high tier weapons from this issue. Its before a chance is even provided to buy insurance, which were my intentions. It's disheartening when this happens, and personally kills my motivation to continue playing
Another one is an exploit that allows people to look through solid walls, by simply using their secondary in first person mode, aiming down sights, and walking against any thin wall.
Also, the accuracy increase gained using prone needs to be excluded from shotguns, as it is tremendously overpowered, allowing people to outclass long ranged weapons with any shotgun.
This one is not really big issues, but something to consider is fixing the ability to instantly recover from prone position with an emote. Alternating the prone and emote button in rapid succession allows the player to slightly levitate and can potentially be used maliciously in conjunction with other exploits.
Lastly, just for the sake of a polished finished product. Knocking the buckets off in the firing range using your avatar resets the ambient music.
