I love how no one would have ever known and therefore never complained about these 'duplicate' item awards before Gree made a thread telling us it was happening.
Correct me if I'm wrong but I didn't see any thread complaining some guy had 132 ixtabspeeders when they should only have 128. We all no how everyone loves a complaint here so why try to fix something that wasn't broke!
If you saw someone's inventory with loads of legendaries you would not question it, you would just think wow they farmed a lot, good on them, and they technically didn't cheat or do anything wrong anyway even if some were duplicates
I find it hilarious that Gree actually created this issue by telling us items would be taken away in a small scale, then just pillaged the majority of players for thousands of times, seemingly targeting the legendary items in a 'random' removal
For goodness sake after all the issues recently you could have just said nothing and there would have been absolutely no complaints about the event (items wise, obviously the server crash was still a huge problem)
Now instead of dealing with people just accepting the server crash as an unfortunate mistake you are going to face thousands of refunds from Google and iTunes, widespread quitting, gold boycott threads and endless more complaints about future problems.
For the record I enjoyed this type of event and it really could have been the event that put the faith back into people to continue playing CC.
Suggestion: re run your repair script in reverse so everyone gets their stats back, no one will complain
