The recent patch that fills unit's icon with red, showing how damaged it is.

This should be fixed so that hovering over the red area shows whatever tooltip was shown when there is no red.

In most situations this doesn't matter, because can click on the unit to see its details.

However there is one situation where it DOES matter:

When a unit has been "killed", it is put in a city, with red over all but the tip of the icon.

But the way to see how many seasons a unit has remaining in its immobilization, is to hover over it and read the tooltip.

Oops - no tooltip now. So don't know how long till it is freed.
