I've been taking a break from ESO to play other games. Mostly Division 2 and Star Trek Online (they're having an event right now.) And I haven't actively played for months. Probably since March or February.
HOWEVER - I am still logging in to check the monthly rewards, and May has a really nice looking camel, so I log in to progress towards it when it unlocks every day in the evening. (I really want that camel!)
And today I logged in, claimed my reward, checked my black smithing mail, and noticed that I had gotten a rewards mail from the Battlegrounds. Even though I haven't participated in the Battlegrounds since probably the middle of 2018 when I was grinding for Caltrops on a new character.
My main concern is someone is logging in and using my account without my knowledge. But I was in the exact same spot in Rivenspire where I logged out near the wayshrine. So I don't know.... Maybe just a bug?
Enclosed is a screen shot of the mail itself. I did not claim it.
Any input is greatly appreciated.
