Description
There appears to be an incompatibility between this version of SoL and First Aid in the most recent 1.19.2 update. It causes player data to not be written properly when saving and exiting a world, resulting in a crash.
I pushed this issue to the SoL repo and was advisedto move it here. (Original post can be found here: https://github.com/tarinoita/Spice-of-Life-Sweet-Potato/issues/13)

Has this bug been investigated at all? I am having the same issue. Sadly I am not confident enough in my Java skills to do much about it.
