Same problem here, even after triying on a new game... and if u dont save often u can end up softlocked in some animations and rooms in the dungeons.
english is not my first language "Ñ" :)
I had the same issue, go into that particular directory, copy and paste any of the rpgmvp files and then rename it that particular file "darkwarrior_3" (no png)
How do i do that
Finaly did it, took me a while to figure it out
