[Rataxes]

I checked with IE and those Mercenaries of Riatvin has a max of -2 AC (if they actually get their dex bonus added on top of their Base AC, otherwise 2)

Either way, none of this makes sense. If I am to believe that my THAC0 really was displayed correctly, then that mercenary should've had to have at least -5 AC to avoid being hit on a roll of 4. If it was not displayed correctly, and I in fact only had THAC0 1. Then he his minimum AC should've been -3 to avoid the blow. If I only have a +9 bonus, which you imply, then he would still need an AC of -1, which he shouldn't have.

Then there's just a FACT that my THAC0 bonus should be 4 + 3 + 3 + 1 = 11
No matter how one twists and turns around everything else, the above must be true. Or else my game is just buggy.
