One of my players had some of the crops error on him when he tried to use Farmer from Actually Additions. So I disabled resourceful crops and restarted the server to clear them since 1.12 doesnt have any plugins or mods yet to delete or clear blocks to my knowledge . So when trying to log in and load the chunk where the error crop is this is the login error i get. Resourceful crops is still on the client though. Also when trying to look at the error crop with the one probe it will crash the client. I also tried to break the crop with a piston because i couldnt look at it without crashing. As soon as i hit the lever to move the piston the server crashed.

Full server crash: https://pastebin.com/xWUjGhWW
Full client crash here: https://pastebin.com/MDQmcQwh

This is trying to log in with resourceful crops disabled on the server but still on the client.
