it really should skip the fight but it might be a bug where rpgmaker runs slightly differently for different people.can you tell me what is said before the freeze?and theres a few ways to get infinite money.
i cant even find anything that says ren should take a few steps but i did find a missing switch so the scene would loop.
so i guess her walking is just... the scene restarting... and her not having anywhere to go to finish the move so it freezes.
easy fix...
will upload new version.
