Starports Vanishing

Definitely a bug, unless you clicked that tile that the starport was on and accidently hit the decommission button? Or think that you may have thought that you had another tile selected, and hit decommission by mistake. If not then it is definitely a bug. I would check this out though, and be careful of which tile your building on, and check what's there before you hit that decommission, or upgrade button! I haven't had this problem, so I'm suspecting a mistake on your part and not a bug, but ot may very well be one! Just follow the advise I gave, and If your still having this problem, then I would take it to Stardock!

Hope this helps in any way!

oops... I meant to type that I could NOT rebuild it. I wouldn't put it past me to have upgraded it to something else, but once it was gone I couldn't rebuild it... even after demolishing another building.

This happened to me too, but only in a Metaverse game. Sadly, no one seems to be able to recreate the bug with my save file.
