All hacks I ever used, will crash sooner or later in normal use, even various vips and privates.
You could probably avoid it by switching off *every* hack after a game ends & you go to lobby.. And re-enable after you go to another room. Most crash seem to happen when a room is loading (and sometimes when a cqc round ends)
It's a very tedious method though so I'm not even going to try it. Can deal with the few crashes every now and then
