I dont know if the 2moons Staff have started to "check" ppls in dungeons to see if they're using hacks, but they CAN check you (or I think so), because when my friend was playing Dekaron EU, he was in crespo dungeon with a party... but he wasnt hacking, but the GM checked him; in theyre party it just appeared PrimePaladin as joined your party, but nobody can saw him he was invisible mode, and he said "I'm here to check Sammy" (Sammy was just an example); so dont be so sure they cant check you in dungeon too, is good to be carefull. PM me if you have any disagreements. If you dont believe me, beilive me I really dont care and beilive me I wont suffer...
And I think is something, to skip this kind of troubles, but I'm telling you again is just a matter of care. And in case of something that you've find the solution DONT POST IT HERE. Dont be sure that acclaim Staff isnt visiting this forum. Keep it for yourself and PM the other users if you wanna be loved ;)
