I was playing my 1.16.5 archive (from 1.14.4 to 1.16.5), and accidentally stepped on the farmland where pumpkin seedlings were planted. As a result, the farmland turned into dirt and the pumpkin seedlings were not destroyed.
My mother tongue is not English, so this passage is machine-translated.
I chose version 1.17 because there are no other versions to choose from
Since you mentioned that this issue occurred in 1.16.5, this report is invalid as outdated versions of the game are not supported.
