An Odd Bug Involving Discarded Pawns And PawnUtility?

[Scottvrakis]

So randomly as I was playing, I was smashed with the console warning me of an error. Usually I just ignore it since it's usually something too small to worry about, like multi-stacked stone chunks or pathing issues, but this one got me with the sheer volume of textvomit that splattered all over my screen, and frankly I'm too worried to continue. I have the logs here:

I know it's a lot to go through, but the problem in question starts from line 970 and onward, saying:
"Warning during generating pawn relations for Man-At-Arms: Pawn Psyche is discarded, yet he was yielded by PawnUtility. Discarding a pawn means that he is no longer managed by anything."

and this is repeated with different pawns until line 1202 whereas I get the last bit of an error there.

Any help would be appreciated, I'm not exactly sure what's happened. I think a raid was supposed to happen, but didn't. Any ideas? Thanks.
