Yup looks like agricraft updated. I will need to update dep and fix on my side. How critical is this for you? I will likely create a hot fix for it just wondering how fast it needs to go out.

We have a player who can't log in and crashes the whole server, but it is ok, he can wait to go to his base until you have time to push. We moved him by editing his playerfile.
