So far, I have seen three issues with the mod. First, the Terran Starbase wasn't upgrading, and second, there is a bug in the mines. If you lay out a field and then right clock to cancel, you get all the money for the entire field back for each mine you clear. Also, the game will let you go way into the red, rather than stopping you at "0".
The mines are also too powerful. You can seed your enitre system with over 750 patterns of them. There needs to be a top on the number allowed, either by tactical slots or just a set number.
