So, you want us to make threads about bugs that have been present for a decent amount of time? Let me just make it easy on you guys and give you a few.
You can glitch with shell loaded shotguns, and team kill.[Presumably snipers too that reload with the same method, like the Kar]
The capsule shop eats your money and gives errors upon opening the capsules.
People are glitching extreme rooms to be easy and getting the exp and rewards.
Pistols eat ammo when spamming, the time between shots the ammo drops by 1 even though a shot isn't being fired, applies to many other weapons as well.
The game will freeze for about 2 seconds multiple times in a game session, then resume.[Confirmed with other players in the same game when it happens].
FPS lag has increased substantially without any changes in settings.
Ping has gone up by about 20 and my location has remained the same down to the inch.
