I belive that to reproduce the issue you need a medal that you can have multiple times (in my case event)then get that medal changed to a diffeent one (by admins) so it doesnt register that you got it that day and then you can get the medal it got changed to again. Thats what i think happend.

I took a bonanza foot zone got the event medal but then it got fixed (the event medal was changed to a bonanza). And then when i took the bike bonanza zone i got a second bonanza medal. I didnt expect to get 2 bonanza medals in one go. I would like to get one of my bonanza medals removed. Thank you.�
