#1 should already be fixed in the upcoming update and happens due to certain explosions. Using [EX] should fix that for now until the patch is live.
#2 weird, shouldn't happen
#3 the game room afk kick time is already 5 minutes, changing it to 3 wouldn't do much difference. I think people maybe be bypassing the kick somehow?
Edit:
#4 I see why that happens. Fixed in the next update.
