Player - Disable/Enable Ability trigger

is it me or it doesnt work?.... im trying to make certain skills that you get later on as quest rewards, by disabling it with triggers at first, and reenabling it later on once you complete the quest, but oddly enough it doesnt seem to work since you still start with them working at the biggining of the game.Those are normal skills, not Hero, and they're skills i made through the txt and slk files...anyone know the problem?

action:
set research level of YOUR ABILITY to 0 (or maybe unavaiable)

actually i fixed it. I had to disable the spell on which i based my own spell.

I'm having a similar problem, but with hero skills. It seems to work absolutely randomly on the disabling side, and never on the enabling side :P
