I left the sim yesterday for a short while and didn't take off my HUD.  I noticed while off sim that it showed me as DEAD.  Figured it was because I wasn't at Outbreak, but when I came back I stayed DEAD.

After about an hour it was bugging me.  I wouldn't reset.  I deleted and got a new HUD.  Same.

Figured if I ate something it might nudge it, so I had some of the moonshine and it did push me to alive but a red splat and pretty hungry and dehydrated.  Drank some more, ate some more, stayed at the pub.

Logged in to hungry and dehydrated again (as if status deteriorated while I as offline).  To test I purchased and ate and drank maybe 10 bottles of water and 10 apples to get me to yellow, and then the food and drink bars still wouldn't fill up!
