Ghost chatbox users?

Hi,
On Monday, I noticed a member on one of my sites had disconnect from the CB at 6:04am, which is 5:04 for them. I asked them about it later, and they said they hadn't been on at that point, because they were sleeping, and they even checked all the history on their family's devices but it never showed up.
It happened again, either today or yesterday, with the same user and the exact disconnect time - 6:04. One of the other members, who gets up early for school, reported seeing me disconnect, too, but when they checked the last online times, the time was around 11pm the night before, as opposed to early that morning.
So, is this some weird glitch? Has anyone else experienced this?

I have never seen this happen on my forums.  Could it be someone has used that account without the member knowing?

We considered that, but wouldn't it show up as them having been online recently?



EDIT: It just happened again, saying a user was disconnected at 10:02am when they were last online at 7:01am.

Bump.

do you happen to have the auto login css active for your chatbox because i get the same thing and just attributed it to that since thats when it started for me. for some reason even if they were on hours before and logged off when i log in several hours later it shows they just logged off the chat even thoughits actually been a few hours.
