World Won't Open after Placing Animals on Minecarts

A few minutes after placing animals on minecarts, the game force closed. I opened the game again and tried to open the world, however it stays stuck at Saving Chunks, then forces closes. Probably happened because one of the carts went near lava (bug already posted).

This keeps repeating, and I am unable to open the world. Other worlds open within the game.
