I've seen the error, but don't know what would be causing it.

Okie Dokie...  I just installed the 18.1 (B8) patch you have for download, and there is a small issue... Zombies just stand around and won't walk anywhere... They will swing at you if you get to close, but won't move after you...  I thought it may have been a patch update error in the game, but I installed a new copy of the game and it works just fine, until I install the Oxide, then the zombies go back to standing in one spot again... No other mods or anything installed...

That's probably where that AI error from your log is coming from then. I'll have to dig around to see what is causing it.
