This one is a hybrid of Starbattle and Heyawake (Heyawacky). Since apparently I haven’t had enough skyscrapers, I keep misnaming this “Skywacky”. Inspiration?
Rules Solve as a regular Star Battle. In addition, connected stretches of empty cells aren’t allowed to cross more than one region border.

Didn’t solve it yet, but the feedback in our mailing list before WPC was, that this puzzle doesn’t have a solution?
Found a unique solution, that doesn’t seem to have any problems (like touching stars or broken Heyawake constraints). Either I’m missing something or one of the mails was a little bit misleading.
Yes, I believe that comment was withdrawn.
