Detailed description of the issue / how can the issue be recreated:
After messing around in some Mystcraft dimensions, I thought I'd relax and do some farming. I made myself a scarecrow out of the melon slices I found, went to place it on an unfarmed block, and my game crashed. When I went to log back in, I got another error report.
