umm
it was during that stupid NUM_FOR_EDICT bug hunt
I put a FNullEnt checking everything single entity...
including the entity that the spray points at...
and if it's null it'll return and not spray..
which it usually is...
in util.cpp
find UTIL_DecalTrace
and find a if (FNullEnt (pHit)) return;
and delete it...
then they should spray once again!
