@Kaysaar i only have one planet atm but i'll go colonize more see what happens. i've finished all research now though so we will see.
edit: after colonizing a second world and docking, ordering some building to be built, and docking again i have three cramped conditions to remove.
edit2: if you need me to do anything (like sending logs, my savegame, or uploading my mod folder etc) i'd be happy to.
edit3: i disabled the whole cramped colony mechanic in grand colonies but the duplication of the planetary condition still happens every time i dock.
