Patch Notes:
- Game/Engine resources should not be modded. Pop-up now informs accordingly and overriding is disabled
-- An in-engine fix to avoid existing mods with already altered data to still override resources will be part of the next game patch
-- This also fixes the issue where combining mods with extensive icon changes could end up with blank icons
-- If your mod altered game/engine resources and you feel this was necessary, please let us know in the forum and we'll look for solutions there
