After the investigation and discussion within staff, we've come to conclusion that the punch bug is a possible VCMP sync problem. It's not any sort of game modification or hacks.
As far as the report for Wall Glitch is concerned, it's an open DM ground. There's a high tendency of players to throw Molotov/grenade. The object's added in the bf loc are intended to save you from your opponent and increase your chances of survival in the battle filed. Thus, WG is not possible there.
Marked as solved. Thanks for reporting!
