YEs both used the same edu's. We even mailed them to eachother to make sure we had the same ones. Or one of our builds was corrupt or It just won't work with 0.81. Something to do with -mod:EB perhaps?

Moros, are you sure you haven't been using anything from our internal builds? For instance, perhaps one of you entered the script fixes we talked about for the hotfix?
100% sure.
