OK, started reading more posts and trying stuff out; and the loadMapChooseTeam thing worked for warping HeroSelect chars to any map in XML2. edited newgame.py
However, just when I thought I was getting the hang of this, the same trick isn't working for me in MUA.
Alll other commands in MUA seem to work like unlockHardDifficulty or unlock char.; But can't get loadmap to work.
Will keep trying.
