There have been a few improvements to the map and to the engine to make this map work better.
A few issues with the map itself were fixed, it got a facelift, and some changes in the 2.6 prereleases have taught the AI how to use consumable units, which made AIs be able to play effectively on the main continent (but not yet explore with ships).
There have been some other non-AI fixes in the 2.6 prereleases fixing some UI glitches the map experiences with 2.5.
I also added the mountain territory effect, but unfortunately we can only use it for territories that are all-mountain, since TripleA doesn't yet support directional territory effects.
Would be interested to hear if people had a chance to try it and have feedback. Cheers!
