Same problem here. I am stuck at 4/5 letters. I get the 5th letter, info about Helen, goal to make breakfast sandwich and spaghetti and it resets. Sometimes resets after letter. I received about 15 or more letters, tools from CID, plants from Lily but it keeps cycling and resetting. I quickly go to neighbour in between but that has no effect. Very frustrating. I get the letter, think I am ready for next part. My breakfast sandwiches have not been counting because it resets before the goal. Parts I have been waiting for disappear. I have force closed many times.
Giving up on this game as it is impossible to progress.
