What's going on with rollbacks. Before I start each chapter I force close then reopen, I upgrade the building, then often close and reopen when first task triggers. When I reopen after force close I get maybe part of task done then there's a rollback, but not everything is effected. I'm on ch 9, and halfway through asking neighbours for merch there was a rollback and all squares became blank again so I started the task of asking again. When I had finished got message that 22 of my requests weren't sent as I had already asked today. Unfortunately this happen every time I request materials, and often have to wait till next chapter and ask again to ge the needed amount. Is there anything that can be done to stop the rollbacks, or is it a bug we just have to live with?????
