Severe warnings, Server Crashing/Stopping

[Crazy-Rain]

So, there's two parts to this. Not sure if It's relevant or not, but I get a Severe warning from TreasureHunting, which first pings me with a mention of being unable to add methods to Hunting. The server seems to still be able to run after that, though.
The next ping being Instrument Error from Misc Changes, it does so Twice, about Could not Instrument com.wurmonline.server.behaviours.MethodsStructure, which seems to be relating to the option to mess with the Carepentry Skill for planning buildings. A little worrysome, but things keep ticking on.
However, this Last one, is where everything jerks to a hault. I get error about the Creature Class being frozen, and then it throws a RuntimeException with the same error, and the server stops.
server.log
Now, I know I have a bundle of mods in there. But I've also tried running it at the Minimum, with just the WyvernMods, and it's Prerequisites, No other mods, and it spits the same error, halting the server.
Unfortunately, I'm not a Modded, so I don't know what is causing it, I have attached the Server Log above, so you can perhaps get an idea of what might be happening. I'd be greatful if you could look into this.

+1 i have same problem. In configuration have disabled most of the options related with creatures. Like titans and etc., but still same exception.

In my fork I know I fixed early loading Creature at one point, but looking back at the commits I'm not entirely sure when. I assume it was PlayerTitles that messed it up somehow, so you might try disabling that, or try out my version.

It is also possible that you are using a module which I am not, and because of this it wasn't a problem for me, therefore I did not fix it.

Ah. Awesome thank you for. Will try both variants.
