Turn #8 and invasion fleet hasn't moved

Thanks for checking it out. I also found that hammering this "static" fleet with artillery makes no impression either. Since they're sitting ducks clearly in view, you'd think they'd be vulnerable to artillery. Not in this game. I hit them repeatedly with every gun in range and only got "No Effect" every time.

I think you're correct that it's "borked".
