Colony slow death by lack of documentation has been a feature of the game ever since my first colony...
with my 10th, it's still an issue.
-I can't figure out the learning rate for schools (with or without teachers) VS internet stations, so I can't pick the most efficient one. Having PLENTY of internet stations who don't require teachers didn't help, the schools didn't help, 99% of population TERMINALLY UNHAPPY from being uneducated from immigration day to the day they die (several centuries played)
-Even with my 10th colony, I frequently can't progress to the next thing before some documentation loophole kills my colony slowly. Sometimes it's because the buildings won't say what I need to build them (what buildbot) and I can't build them and I don't know why for months. People don't anwser these questions when I asked in forums. It REALLY should be a part of the game explaining "why can't I build this?" under a "cannot build even if you had ressources" type submenu.
-The game should give me a popup once in a blue moon if I need more atmosphere to get to the next level. I was stalled for 2 entire years the last time that info was missing.
-I still have colonies becoming "Everyone has a job, everyone is happy, everyone has food and water, everyone is off duty all of the real life day I try desperately to produce 2 microship more or 255 science more to get something" and putting no-rendering-colonists and other performance friendly options, nothing seems to help.
-At my 10th city, I still can't get halfway thru the game, and still have 3 to 4 different unexplained problems EACH TIME
-The game needs a NPC robot advisor to give you some GODDAMN HINTS once in a while. YES, REALLY. With a capacity to turn it off once you learn what the game should have explained in tooltips all along.
