This sounds similar to something else we ran into not too long ago. I believe the problems lies within a new item we put into place. Wherein, if you select a Gladiator, the Achievement or whatever that was it's prerequisite automatically gets added and verified to your Character, if it wasn't there already.
Example:
You selected the "Marshal" Accolade, all 5 of it's Prereqs (Paragon of Vice, The Mongoose, The Next Big Thing, Weapon of Mass Destruction and Annihilator) would be checked and added/verified to your Character if they weren't present before. The problem we encountered before was where this item didn't work 100% as intended...somehow, other Badges were being added. The best thing to help us figure out this bug is to track down the Badges that did get added to your Character on the Site, that he/she actually doesn't have, and list them here.
*Edit, Found the other Thread (
Linky) regarding this issue. This item is apparently reading the Pre-req Badges and adding the resulting unlocked Badges as well, even if the Character does not have all the Pre-reqs. Meaning, you have 3 of the 5 Pre-reqs listed above for "Marshal", however, the Site sees just 1 of those Badges and assumes that you have all 6 Badges total, and Adds/Verifies them all.
