I'd like to disable the changes to food stack size but what I'm doing isn't working. I've set:

Changes the stack size of food to be dependant on the food's replenishment value

B:modifyFoodStackSize=false

but it doesn't seem to have any effect. Is this setting dependent on another or is this a bug?

Edit: I haven't been able to test this much yet but the reason for me asking relates to Harvestcraft mutton. In my survival game it is only stacking to 3. The raw beef in that game however is stacking (or at least it's up to 5). I've gone into a test world and haven't been able to replicate it, though. I grabbed a stack of sheep spawn eggs, switched into survival, spawned the sheep and killed them. Under those circumstances, the Harvestcraft mutton is stacking.
Edit again: Apologies. Stack size is indeed working. The issue I was seeing possibly related to food collected before I disabled stack size. Either way, I can't replicate it in a new world so I'll just eat the offending food and get on with my game. Cheers.

Soo...is it working now? Is this issue valid still?

Very invalid, it seems and I'm all embarrassed to have wasted your time
