An important thing for the gms to remember is that they shouldn't teleport when they are invisible, this has happend to me with alot of different gm's and every time it happend i got my ass debugged, by cooincidence i died when zaki teleported to me, but for him this bug was unknown so hes forgiven and we solved the problems together.
So for each and every single one of the gms, take this as a tip.
When invisible don't teleport to players
