It seems if I name my new entity files using existing ones, it seems fine.
But when I rename them as new entity files I got minidump.
For example, say I have a new entity file for Kol battleship for buff.
When I name this file "BuffLowCostAbilities.entity" I have no problem.
But when I name this file "BuffAdaptiveTarget.entity" (which does not exist in original files), I got minidump.
Is there any way to fix this?
