Curse on Hit Won't Trigger

Have CURSE-ON-HIT linked to FLAMMABILITY and PUNISHMENT. I have not seen it trigger, ever. I have tried it with SPLIT-ARROW, EXPLOSIVE ARROW and just regular old attack. Nothing. Experimented on lower levels and cleared them out without ever triggering a CURSE-ON-HIT. The gem is currently at 38% probability to curse.

Definitely a BUG here.

I looked at similiar threads and there doesn't seem to be any issues like this.

Thanks.

EDIT: Never mind. I got it. I am a dumbsh!t
