Hi on my play through, it was sometimes hard to place improvements where I wanted it would auto place items in what I guess might be the best place for the bonuses

Improvements would be placed on the same place as the last queued item, or they might be on the build list but not on the planet map.

It seems I could queue more improvements than I had space for, I didn't seen a means for upgrading any improvements or older improvements being replaced in the menu with the better version, e.g. colonial farm with the food distribution facility

Lastly I got stuck when one planet wouldn't build anything or go into producing something or rather it had items in the build queue but they weren't regesitering , so the end turn was stuck on idle colony...

hope these get fixed
