I don't know whether thess are related, but I think it might be just a temporary display issue.
Say you pick up a corpse and it places you into Overburdened! and then your attempt at cooking the corpse fails. The display still shows you as Overburdened!
When you start moving or do anything else it changes to Strained! and life goes on.
Say you eat an ant and vomit the display will say you are not hungry, but as soon as you do something your status changes to hungry.
This bug sounds like something similar, but I'll be happy to create seperate reports if it's not related.
