When I had this happen I was on yellow thirsty and no message on hungry, The Server went down and when I logged back in I was suddenly starving to death and dying of thirst.

Same here, server did a reboot on schedule and informed me five and one minute before the restart. I stayed till the message of no response. Back then I was healthy, energized, hydrated and 1st level of stuffed. I waited a short time and relogged to the same server. There I got red messages of starvation and dehydration and thought those are fake (messages of the day). When the screen grayed out I knew this was for real and barely survived.

My friend did the same but his login took a bit longer. He was just fine.

As pointed out by snipertrifle, drinking from 20L jerry can be the reason. Back then I tried filling an emptied can with rainwater to see if a jerry can fills with same percentage or with same absolute volume per catch. Later one is the case and after filling up about 700ml I drunk the collected water all at once.

Confirmed. Anybody know how to reproduce this?

Apparently if you drink out of a full 20l jerrycan then relog, the game thinks you are stuffed and have thrown up many times, leading you to be dying of starvation and dehydration :)

i can confirm some players (a frind of mine) have this issue, i don't know what causes it though...
maybe i should just kill her and see if it persists

also use search, as this has already bben reported
