I found a bug whereby entertainment buildings will lose all their entertainment slots for colonists, while tourist slots are kept. The entertainment data in Statistics page will also display a negative number (vacant slots: - xx). This will then cause approval rating to start dropping significantly, as I presume the game is seeing that there isn't any available entertainment.
I play in web browser version from the My Colony site.
A few observations :
- Reloading the game fixes it but only temporarily. After some seemingly random amount of time (sometimes only after a few minutes, sometimes hours), the bug returns.
- Tried reloading an earlier save, about 10-15 play-hours before, and the bug eventually returns after a few hours.
Based on what entertainment buildings I have, this affects most such as pubs, hipster bars, pyramids, parks, green domes, stadium. Surprisingly Arcade Center and Colonimulation Hub don't seem to be affected, but building a few of them didn't seem to improve the approval rating from dropping.
Somebody else on the general chat was also affected similarly as well.
Edit : Arcade Center and Colonimulation Hub are affected as well.
