If you do this:
msg(mary.alias)
game.pov = mary
msg(mary.alias)
You will find that Mary's alias is changed to "me". I can see why that happens, and it gets changed back when the POV changes again, which is all well and good, but I want to stop it happening. I guess somewhere something is watching for game.pov to change, but I do not know where. Can anyone point me in the right direction?
