Meh. I’m tired and am not doing more screen shots right now. haha 
But all evidence so far DOES seem to point to region restrictions being the problem.
I had tested some immortals outside their “area.” But that meant they had to fit the restriction. Because…
It definitely appears that the problem code is in whatever allows immortals to bi-pass restrictions in their “home” region. This is made concrete by the immortal whose home region happens to have a restriction that fits. (team does not get erased.)
Meanwhile… to nobody in particular… how does this stuff get through testing? Even automated testing should catch something like this.
