Me and my friends are experiencing weird healthy status behaviour.

Lets say we have PLENTY of food, we are constantly stuffed to the teeth both with food and water.

But still its hard to get healthy, where it was easy before. Only if we get hit and heal its showing for a while. For example, we get hit by a zombie, patch us up with alcohol clean the wounds and put bandages on. As long as our wounds are not clean we have healthy. As soon as they are clean, its gone. And its normally not coming back. No matter how much we stuff ourselves with food and water and wait...

It looks like the system is showing the wrong status. Why else would we be "healing" even without showing "healthy" status.
