This appears to be caused by Mine and Blade trying to find out what a maid has in its second hand slot (a Mine and Blade feature). Mine and Blade casts the maids inventory to its InventoryPlayerBattle to use this second hand slot method but crashes since maids extend the InventoryPlayer and are not an instance of InventoryPlayerBattle. A check on the Mine and Blade side to see if the entity inventory is a InventoryPlayer and not InventoryPlayerBattle would be the simplest way to solve this bug.

A check has been placed into the Battlegear2's AbsractMBArrow that solves the issue.
It is up to BattleGear2's Developer to implement into a release.
