Few sugg.

Putting an option for zp/gp/all guns if your'e making a room

If you picked up an item from the ground (specially in em),it shouldnt switch
for e.g. you already have a gun/pistol but no nade,when you picked the nade it shoudn't change from gun to nade it should just stay to gun.

Adding few errors that will kick the obvious hackers out from the room,or making the errors work little bit faster

Add new hats or accessories only for gp

Giving 700 exp for playing 5 hours (not given if players went afk,should be ingame)

Just a few suggestions the came in my head.
