Expected Behavior

Game to not crash when holding a charge-able item in the offhand

Actual Behavior

These lines in ArmorUtils add a singleton list to the pair map. This is then retreived in these lines in AdvancedNanoMuscleSuite and an iterator is used. There are calls to Iterator.remove(), which a singleton list does not support, and throws a UnsupportedOperationException which crashes the game.

Steps to Reproduce

Have a charge-able item in your offhand, and make sure that charging is enabled on the Advanced Nano armor and that the armor is equipped. the game will crash in 5 seconds or sooner.
