Caves Reset Completely with my usual entrance taking me to a different location?

I had been fighting with my merms against Lunar Bearger, my game froze, I exited out, came back beat him without turning them lunar, then went into the caves and it was all gone. I am hoping there is some way for me to go into the save folder and retrieve an old save for my caves, or at least fix the caves entrances?
