Haha, that's great. Sucks, but great. It's on our list with a fix coming in the next update:
Pretty uncommon, but its third trait triggered both times on this bug, creating two copies of the one troop.
@EnsignGarak: Thanks for the report! We'll keep investigating the cause of this hang. In general though you should receive your rewards - we edit your keys/currencies on our server before it returns. So while you may not receive a confirmation/unlock screen, 99% of the time you will receive your items. If not, and the mail isn't there, contact support for the missing items and they'll investigate.
I believe the crashes that were mentioned were part of the server issues we were experiencing yesterday. Will investigate the PvP and Revenge match task. Thanks everyone
