This is one of those maps that would benefit from an increase in values in TripleA.vmoptions file.
Another World has - lots of territories, triggers, players

This is my temporary fix, it works will for me and no one has posted a complaint

These maps benefit from the vmoptions increases
Warcraft: Hero Wars - very large map, lots of territories & triggers
The Shogun - very large map, lots of triggers, players & politics
270BC Wars - lots of triggers & players
War of the Relics - lots of triggers
Another World - lots of territories, triggers, players

Perhaps a fix could be at the install of TripleA test the users RAM and size the TripleA.vmoptions contents accordingly?
