It adds food automatically to the lunch box however...

Let's say you have 6 stacks of 64, it adds 2 of each food item, but the rest of the food in the chest is deleted. As if you had added 64 of each food item to the lunch box, but only ended with 2 of each with the rest just disappearing.

currently I just switched the max stacks to 64, but that kinda ruins the whole difficulty thing :P

What version of the mod are you using, and which Minecraft version are you playing?

SpiceOfLife-mc1.11.2-1.3.8
AppleCore-mc1.11.2-2.1.1

Minecraft 1.11.2

This is a new bug introduced in the 1.11.2 version. Will try to get it fixed soon.

Just fyi this issue still seems to exist. Is this going to be resolved for 1.11.2?

Yeah, I really messed up the 1.11.2 port and have been dragging my feet on getting it fixed, sorry. Will have another go at fixing it now.

Should be fixed in the next version.
