Hello,
The plant feature doesn't work when the crops are planted on dirt at layer 1.
I'm not sure what causes this bug but I think it's the farmland gap that puts the ground at Y=0.93750
Symptoms :
When bot is placed on a crop and command /minebot plant is executed, it breaks the crop, replant it then totally hangs.
"An another strategy took over"
When putting a little farm area on layer Y=2 it runs just fine
Using Minebot 1.8, as 1.15.2 doesn't have the plant feature
