I was just in world and all of a sudden when I was trying to add someone, the screen dimmed out and I couldn't click anything so I refreshed and went to my homepage and I was somehow logged out?? I just signed back in & everything seems ok but wtf?"

It could be that your session timed out. WeeWorld does not allow users to remain signed-in for indefinite periods of time for safety reasons.

Another possibility is that your sign-in cookie was invalidated for whatever reason, and needed to be refreshed.

In either case, it is normal, and not something to be concerned about.
