i have the problem on the map Fortress.

the thing is, it's quite random, mainly happens when going to PAP, going down the ramp to the power area, or opening the area to banana colada..?
it typically happens when i start running in random places

i have a problem with the game..... everytime i run down a ramp or to the pap, it says: cheat detected, noclip.... .WHYYY?
