Do anything that changes status of an item - e.g. mend "badly damaged" pants with sewing kit
Mouseover item - status is not changed
Inspect item - still no change
Exit/enter inventory - no change
It still says "badly damaged" for like a minute, then changes to "worn"
It work the other way as well:
- Have a can of beans
- Get hit by a zombie
- Beans are pristine, but when you you try to eat them it says "too damaged"
- Inspect beans, says pristine
- Move beans in inventory and/or wait a minute, and it changes to "ruined"
