I am making my own version of an eating, drinking, sleeping mod. Not because the existing ones are bad, but because I prefer the effects in a slightly different way. And besides, it's good practice. However, this one is slowly driving me nuts!

Actually, everything seems to work now. EXCEPT that eating certain types of food has no effect at all.
I have created a scripted fire-and-forget magic effect which calls a quest method. This method just increases a counter determining the level of hunger. The magic effect has been added to all food potions. It works well for, say, Grilled Rabbit (and others), and my debugging messages and the hunger effects are acting as expected. But for some diffuse reason it doesn't work for Cooked Venison (and others) - the magic effect doesn't seem to be triggered at all when eating that food item.

I have run out of both ideas and patience, so I thought I would ask here. Do any of you have any ideas what the problem could be? Advice would be much appreciated.
