massive spam in server log after update PeiAI&cats&wolfs to 1.4.0 about petai HOT 5 CLOSED

Is there an initial exception prior to this?
Is there action you have done before the serverlog got spammed?

from petai.

We are getting this as well, and cannot play at all (essentially it starts happening as soon as a player logs in)

Best we can tell, this happened when one of our players was putting some limonite nuggets in a bloomery. However it's probably much more likely tied to the tamed Cats nearby. We just updated Cats + PetAI earlier today to latest versions.

As best as I can see, there is no previous exception between the server starting and this (we don't have the log from the original crash):

From logs/server-main.txt:

I hope this fixes the issue.
I am going to upload this directly to the moddb too to prevent people from running into this issue.
If someone left a little feedback if it worked that would be really great. I am going to leave this Issue open until i am certain that this is handled properly.
