Describe the issue
Causes Java exception when right clicking on wild flax, which isn't on farmland but is harvestable by breaking it. In singleplayer this just outputs to the debug log, untested in multipplayer.

Hello,
in case it can help, I got a very similar issue (same exception, same line) by auto-mealing+harvesting potatoes with 2 Deployers from the create mod.

Full crash log here :
crash-2020-05-17_22.12.58-server.txt

It corrupted the world and I had to restore a previous backup so it got pretty bad for me :'(

Thanks for your work on the mod!
