Thank you for reporting. Does this happen frequently or was this a one time crash?
Will fix it regardsless, just to decide if I should release a new version just for this

Honestly, not sure. After removing the entity with NBTEdit I used the In Control! mod to disable advanced vampires from spawning. Haven't had a crash since then.

Unfortunately, I can't really figure out what could be causing this crash. At the position of the crash log stacktrace mentions, nothing should be able to cause that exception. So there might another core mod messing with Minecraft's source code.

Interesting. Not sure what mod could be causing it. Regardless, I just got another crash for the same reason (crash log) with a normal vampire, so it looks like it's not a one-time thing. If you could publish an update with the workaround, that would be awesome.
