I noticed that in most campaign levels the AI doesn't seem to build new units.
This makes some missions, such as the Raid on Bespin, really easy as all you have to do is survive the initial onslaught and you can just dismantle the enemy bases.

Is that normal? In some missions the AI does send raids but I'm not sure if they are actually being recruited or if they are event spawns.

I tried just running the original SWBG executable but there doesn't seem to be music? Is there a way to fix that?
