The server crashes everytime I right click a wolf to sit it down while I have the Astral Tome book in my hand. this is the crash report
crash-2018-01-16_00.42.12-server.txt

Also, the dog may be corrupted. Maybe it's the way I sat the dog down but I dunno. the FTB Revelation version is 1.2.0

That crash log is an NPE for the AI. I really don't think AS has anything to do with that, especially since it's not even in the stack trace.

What happens if there's no Tome in your hand?

I doubt this is on AS' end

Works fine for me,
Direwolf 1.12 modpack
Astral Sorcery 1.8.4

@JedTheSeeker any other information to indicate this is an AS issue at all?
