Comment 1 for bug 1249682

A similar issue happened to me several times in in a multiplayer game when you cancel the production of a structure and immediately start producing it again. However, while no cameos where darkened then, the production still went normally, the structure was "ready" when the timer finished, and when i placed it everything went back to normal.

I also didn't try to cancel my building construction when i got this issue, that might be the reason why it could finish.

This happened first time with one Ares update, but i don't really remember which one (probably some 0.3 build).
