I was able to control another player's airline R2

I should mention I've played the game for years and never have changed my password.  I either remain logged in, or use autofill to quickly log back in when prompted.

Yesterday when world's reset, as expected my airlines were no longer there.  However when I clicked on My Airlines another carrier showed up for R2

One that I did not start, or accept control of.  My username and photo showed me as logged in.

I clicked through a few prompts to if I'd be able to make changes and was able to.

In theory I could have closed their routes, sold their planes, etc, etc.

I thought I had been hacked...........but why.  Who would want to take over my random AE account.

Only to start a very simple airline.  I logged myself out.  I logged back in with my regular password and it was gone I was back to no airlines as I expected.

Today was normal as well.

I don't know if anyone else has ever experienced that.
