Quite weird. Is there anything in the console?

On selection of fairy via gear
SCRIPT ERROR: slavegear: Invalid get index 'Null' (on base: 'Dictionary').
At: res://files/inventory.gdc:330.
Same error when trying to equip with clothing and also same error when unequiping clothing from another character.
also same error when unequipping, hence duplicating from fairy by selecting character with same clothing fairy wears, then changing to fairy and unequiping without actually doing so. fairy only get's unequipped after unequipping different charakter with same clothing.
