Today i submitted a screen with this bug to me hapened like this
First i created an outpost ship a succeded colonize a planet (when i clicked the ship i saw the menu to colonize)
Second i created another outpost ship i went to the desired planet but can't see the colonize button after i couldn't move the ship for some hours after another few hours i succeded move the ship but can't colonize another planet.
This is a bug or i am doing something wrong or there is a limit of colonies that i can have
