Purchased 25M worth of rat traps, game said lost connection, lost the xp

I'm planting a crop of KeMs that's approximately 17x9, every 4 hrs. The only crashes I'm worried about are when the xp payout is floating. So I tap and collect them in groups of 10. I've had only two crashes doing it this way, where I lost the chance for the donut box. But I'm not worried about it because as long as I have a crop growing, whenever I log in i get a donut box immediately that's not in sync with the xp meter or anything else. Confusing but very welcome
