hello anyone there!

Don't expect an immediate reply on this forum. People rarely check it.

As to your problem, I'm not exactly sure what you are talking about. What do you mean by "the map doesn't explore even after units move over it?"

As for the workers destroying buildings, that means you are telling them to raze them and not upgrade them.

I got my old copy of the game and thus problem solved. I think it was a bad pirated copy online (as it's not available in my country on steam).
