I tried to place a solar panel to the side of a block right under the world border and because the solar panel has multiple blocks it wouldn't normally let me place but this time I crashed. It might have to do with the recent update. If you need more info let me know.

I couldn't log into the world until I disabled better foliage

Fixed with BF 2.3.1
