When the arena weeks changed it was possible to try and reconnect and be awarded another medal if you had won one that week. Several attempts led to several medals. Rovio were informed about this so it looks like they take the servers off line while they update.
Regarding a better award than your league finishing position shows maybe down to the fact we are in several leagues but should only see one. Obviously this doesn’t happen as players get bounced or appear to be bounced around but are probably just seeing other leagues and maybe the rewards are from an alternate league where you did finish 5th ?
