Caves to Surface Rollback crash

I was down in the ruins and died. Because no one was on with me I rolled back. This caused me to rollback to after I was dead. I opened the menu and rolled back many times. One time it was before I was dead. I took one step and my game crashed. I closed my game and re-opened it. When I hosted the server again (this time with a friend splitscreening with me), it took a long time to load. Once it loaded I was on the surface not near anything that could lead me back underground. My friend was still in the caves.
