I'm not sure how the saving mechanism works in this game, but I've noticed that if I close the game immediately after doing something, it won't save and when opening the game it never happened. For example, starting a tree removal and then closing the game sometimes doesn't register and I would have waited up to 2 hours for nothing. This also just happened where I needed to restart after visiting someone, and when I came back I lost my ticket and got no rewards, meaning the save happened in between using the ticket and collecting rewards. So my suggestion is that whenever you close the activity on Discord the game saves first, then closes. Although, I'm not sure if this is possible under Discord's activity feature, as the "Leave Activity" button might override or ignore in-game commands. If that's the case, then maybe some sort of in-game button or method to manually save your own progress to the server, probably with a cooldown, to prevent spamming and overload. Not sure if any of this is feasible, but losing progress is quite a large issue in my opinion.
