Hello @wheat ridge, thank you for your response!
I’ve only been playing the game on my iPad.
I’ve been playing since the AA version came out, so it has saved progress across several days.
I’ve only played at home, connected to WiFi, never offline.
Details about rollback: I had been playing the game. I switched to YT so I could load a video to play in the MiniPlayer. When I switched back to the game, the title screen popped up, which I assumed meant the game crashed. When the game loaded in, it played some story dialogue before forcing me to play Level 4. I closed the game and reopened it but it kept doing the same thing—forcing me to play Level 4. I played the level and found that the game had basically bumped me back to that point. All of my workers, upgrades, etc were lost.
I didn’t get any messages about saves or syncing.
Thank you!
