Steps:
1. Save (or equip) any gearset on one platform or device (PC or PS3)
2. Logout, then login to the same character on another device (PC or PS3)
3. Change the main veapon, then save as a new gear set (might not be neccessary to actually as the set).
4. Logout, then login to the same character back on the first device (PC or PS3)
5. Character is now displayed with an incorrect / missmatched gearset and class (let's say Class is Miner and gear set is Botanist)
6. You're unable to (re-)apply the curent gearset to the Character (option is inactive / missing) and only option is to switch to another gearset first and then back to the current set or to change the main weapon first manually. This could also lead to accidental overwriting of the current set with incorrect gear if you choose the option to update the gearset.
