Have the same issue AGAIN. Had a full bot and was back again to 0 this morning. Both on my cell and tablet. This is becoming more and more annoying. Compensate people of fix this!
Wow that's why I keep losing it. But then I won't try to rebuild as long as this isn't fixed. It costs me a lot of boosters to get it to the max and then if you keep losing it every random moment work is being done! Can I get a message at the moment this issue is fixed?
