Okay so my city is at around 114,000 people and it was growing pretty good with around 150 people increase in population per week. But then I built the space elevator and now the population is decreasing by around 2000 per week. Is it normal for all players whenever the space elevator? My city is not showing any big problems as of now.

I’ve shown my city here and I’ve circled the population bar. Please let me know what the problem is
