Hmm. Strange. I am unsure what this could entail then. That's what SHOULD happen to Kerfur, in theory, but mine always got destroyed by the EMP orb. By any chance, do you have prop impact physics on? At least, I think that's what it's called.
Hmm. I'm unsure then, being honest. He shouldn't operate on battery anymore, to my knowledge, so if it's not the EMP orbs, it might be an event for Kerfur specifically.
On another note, how do I FIND these EMP orbs? They are getting REALLY annoying... this is the seventh time now that I've had to rebuild Keith. Edit: Ninth.
I've just realized; the last time I actually SAW one was several days ago, so it might be some undocumented anomaly. My transformers have been dying a lot recently too, so maybe there is something in my save i need to vaporize.
Hmm. I noticed it starting to happen when the cyborg boars came out to play for the first time. Though, if that were the case, I feel like they'd just destroy Kerfur flatout.
