Ignore the upgrade "numbers". All the upgrades are still there regardless. The AI upgrading is completely random, so sometimes they'll research lots of attack and no armor and vise versa. Generally they upgrade fairl even across the board. Just whatever they upgrade first get the "number" displayed next to the icon. whether it be attack, armor, HP, ect. Also keep in mind some upgrades only apply to units that spawn
after the upgrade is finished, while others apply to all units immediatly. As for clumps of units not doing anything, I have a periodic event that gets them moving again (only if the units are owned by the computer). There is very limited AI support, but the slots have to be filled with computer players, but even then all the'll do is upgrade and attack-move the spawned units to the center and then to the enemy beachheads. I debated importing music, but it simply would have increased the file size too much. Instead, just the default music plays. Thanks for the feedback!
You may think the boats have a lot of HP, but when its late game and a lot of upgrades have been researched, it can lose them pretty fast.
