Is the game’s on-device data or update process particularly fragile? There are a lot of bugs after update or apparent (device or account?) state changes like: monuments giving non-event drops during an event. Egg missions changing the number of tokens they reward at the wrong time. And then graphics getting corrupted: snowflakes on lightning towers, Leo’s pointy shield, a texture missing from the floor of the training den.
Often the suggestion is a hard reset and a reinstall, but the game is big and that’s an annoying process to go through regularly. Are you able to reproduce these scenarios and identify underlying issues?
Edit: I’d class rollbacks with these bad state things maybe. Not big ones, but the thing where you come back to the game and most of what you did for the last N minutes never happened. Roster changes not saved. Egg missions not completed, XP runs not done. Sometimes the egg missions are different too. It’s utterly maddening.
