Issue description

When combining 2 freshly crafted, empty, uncolored backpacks. The game crashed.
with "The game crashed whilst container click
Error: java.lang.ArithmeticException: / by zero"

I did previously combined some and it worked. Just now I colored one backpack and combining with that one now worked.
Im guessing the missing color is the issue.

Steps to reproduce

0. Play ATM9
1. Get two basic unmodified backpacks.
2. Combine them in your inventory with right click
3. Should crash

Other information

I am playing ATM9 0.3.2 btw.

Does ATM9 add the backpack to a blacklist for sorting mods? If not, please never sort inventory in backpack inv :D See #66
