game messes with my inventory, armory chest and classes

Time: every time i start the game
Frequency:always since a week
World name: cerberus
Character name: kiekebeest ragnarak
Class/Level: dragoon, leatherworker, pugilist

the small issue is that the game reorders everything in my inventory and armory chest every time a start the game. But the less funny thing is that it kicks out gear of every class I have. So my Dragoon is level 76, but when i start the game, it states I'm level 74 with no pants and gauntlets and that this gear is missing, while it is still in my armory chest. My level 19 leatherworker preset is deleted every time. And when I start the game as a leatherworker I have no actions, so I have to insert every one of them back in my hotbar manually. My level 16 pugilist loses her pants as well when equiped :p so I'll call it a perv bug XD

hope you guys can help me out, because it starts to get annoying :p

This IS a problem that SE needs to fix.

However, here's a solution to help for the time being.

Delete ALL gear sets. Every one. Wait about 10 minutes before you log out after rearranging all bags and deleting said gear sets. This lets the data centers recognize and save those actions.

Next time you log in, remake the gear sets, check your bags and everything should be dandy.
