I'm not saying this isn't a bug, but I get this on PC when I play on my laptop and my desktop alternately. When I log in on one or the other the last class I had equipped on that machine is shown as the gear set, meanwhile the equipped set is the set I used last on the OTHER machine. What I'm asking is, are SURE you are the only one that has access to this account? There's some shady sh!t going on with highjacked accounts doing scam shouts. It's more likely something innocuous like you theorized earlier but perhaps consider a password change as part of your troubleshooting.
