Try changing your rendering system, or maybe uninstall and reinstall the game. I used to crash a lot, but then it stopped once I reinstalled it. Also, if you're crashing when trying to enter on a certain character, then make sure it's home is reset and it's at the new lonely cave. That's pretty much all the things I can come up with for this situation. I hope this helps! If you explain more on where you're crashing at, then I may be able to help more.
