So the way it works as I know it is, you deposit your Grem-Aliens in a friends town and after 4hours you get some bounty; for Phase 1 it was probes now that we are in Phase 2 it's ray guns... After 4 hours each Grem-Alien is to return with 4 ray guns or 2 ray guns (if your friend squished it) to which you get a notification telling you how many you've got from your Grem-Aliens being in your friends towns.
I'm having a problem where I send Grem-Aliens into other towns, log in well over 4 hours later and get no notification that I've got anything back! It's quite frustrating when you've launched 20 Grem-Aliens or more like I have and get nothing. Also my ray gun totals don't go up! So it's not like I've merely missed the notification, which means it's like I never sent them in the first place! I've been keeping an eye on this and it's really frustrating. Is anyone else having this really annoying problem?
