GetResistFire, getResistFrost and getResistShock doesn't work as in vanilla
It's a minor bug that I still wondered if it was worth talking about. But, probably, it is necessary to tell, otherwise this bug will remain unfixed.
The commands getResistFire, getResistFrost and getResistShock take into account the action of weaknesses, resistances, modResistFire, modResistFrost, modResistShock, setResistFire, setResistFrost and setResistShock, but action of Fire Shield, Frost Shield and Shock Shield is not.
The Shields themselves work correctly (in particular, increases resistance).
