Some of my crops seem to become entities (jump out of the ground) spontaneously.
It is on a public server in a protected region, including when the crop is in a house with a lockette door.

Put the summary of the bug you're having here
Some times when I log in I find that planted crops have become entities or disappeared. Log block does not show any actions taken to harvest the crop by me or others.

This happens most to sugar cane when it is next to water which is located in a neighbouring chunk

It also happens to cocoa when it is attached to a wood block which is located in a neighbouring trunk

Steps to Reproduce:
1. Dig a water channel along the eastern end of a chunk
2. Plant the sugar cane along side the channel, on the neighbouring chunk (East of the water channel)
3. Head East a long way (whatever it takes to unload both the water channel chunk and the sugar cane chunk
4. Head back West so that each of the chunks load one after the other
5. Sugar cane will no longer be planted
