Weird chat malfunction

For some reason, in my club The Club for the Kings, it said there was someone else who was on the chat page, but that person wasn’t even in the club, and also was only online one hour ago. Here is a screenshot.

It's not a bug. They were a member of the club. Check your audit log

I know but they left and were still in the chat after being offline for an hour

The chat session may stay live for a while and it's possible they left the chat tab up and left the club via another one.

If it's still there in a few hours, there may be an issue with session clearing when a member quits a club
