Currently signed into someones account on Bungie.net, using an icognito tab to post from my regular account. Never heard of this person or the username. Playing on brand new laptop that I've kept on me 24/7 for the past few months. No weird activity on my Mozilla account. Discovered after trying to sign into DIM, and was told I was using the unknown account. Currently trying to contact the account owner, but would also like some help from Bungie Support if possible. Thanks in advance.
