there is a way to make a map unopenable in that trigger viewer! need a hexeditor though and in hex make 16 open slots at the end of a chk file and in those slots (also in hex) type 03,c2,01,c2,01,c2,01,c2,01,c2,01,c2,01,c2,01,c2
it should not be able to be opened after that because it creates a corruption data or something in the map that i found out when i was bored
