Summary

0004446: Grazing hungry animals eat slower - snowballs starvation

Description

Akin to 4113, and I can't entirely confirm this, though it seems likely.

Hunger tends to slow down all activities. One of these activities, one would imagine, is eating. Since larger animals need to feed -all- the time in order to survive, some animals that could normally survive in the current setting cannot if they fall into hunger. Because they're hungry, they eat slower - and because they eat slower, their rate of intake can drop below sustenance.

This seems to be especially true with Yaks, who are borderline. If a Yak becomes hungry, he will inevitably die even if given plenty of pasture.

Steps To Reproduce

Start a fortress with a Yak or two. Wait for the Yak to get hungry before assigning it to a pasture. The Yak will constantly eat, but too slowly to survive, thus ultimately dying.

Additional Information

While similar to 4113 and a possible reason, the two are different bugs. 4113 has a general problem that some animals cannot sustain themselves even if eating all the time. This bug is more akin to a specific problem - the possibility that hunger is causing a decrease in eating speed, leading to a snowball effect.
