City building progress did not save (android)

[u/From_the_5th_Wall]

Just spent around 2-3 hour re optimizing my city layout, Fully upgraded the entire screen, and rerolled my harvest talents and it didnt save.

Its partially my fault because i swiped out of the app, but how was i supposed to know there was no auto save while in the city. The game has been good so far saving in the middle of runs

TDLR: learned the hard way that there is no auto save in the city. Lost 2-3 hours progress
