Okay, I pushed out an update that should fix it. I can't tell since I can't recreate the bug to check, but I hope it works.
Hm, sorry, I'm not sure what's causing it, but I believe it's some kind of compatibility problem? A cursory google search lead me to this: https://forums.rpgmakerweb.com/index.php?threads/rpg-maker-mv-games-graphics-wil...
Edit: Actually, there seems to be a plugin or sorts for this? Let me test it out really quick.
