Quite simply, where the ai works on the map in XI, it gets slower and slower and eventually crashes, Every time. The last build was far more stable. I could play a game against ai opponents who functioned properly. Now the ai (qbot for example) doesn't work, or spews errors messages if it works and creates units, structures and attacks the player, or it appears to works, slow more and more, then crashes. I might try all the maps, but this build seems inferior to earlier ones having regard to playability. How does a person access the SVN build? It probably works well, and it would be less frustrating as these errors are probably nixed.
