It's amazing how much you have done for the limited time we had! The amount of buildings and units is really impressive!
There is some optimization issues. At 100 nubs the game began to have lag spikes and when selecting expansion packs they began to change really fast. I left the game open for 2 minutes at the end and it crashed.
Yeah the flashing expansions thing is a bug I thought I fixed, it happens after you have 3 or more expansions because it tries to reroll ones you already have but since there is not other one you don't have it'll keep cycling through forever.
As for optimization there wasn't a whole lot I could think of to do without causing some weird collision issues, maybe I'll try again in the future
