Alright, for some reason, I was able to open it back in Kimera. It doesn't make sense. I tried the sword, it couldn't load it, I tried a different one that wouldn't work before, it opened fine, then tried the sword and it opened fine. Anyway, I looked and it was set to 25% already
so I saved it and it works in game.
EDIT: Oh yeah, I re-extracted your RAR, so it overwrote it with the original 25% one.
It seems as though opening it and saving it makes it work, even without changing anything.
