Steps to recreate:
[LIST=1]
[*]In the editor, File->New
[*]Place a 'Fire' enemy on the screen
[*]Test the quest
[*]Walk into the fire repeatedly
[*]Observe the fullmost heart correctly becomes white from right to left, but the other two become white from left to right.

The hurting happens in gamedata::set_life
Commenting out the body of lifemeter in subscr.cpp doesn't have any affect on this bug.
The hearts are drawn by SW_GaugePiece::draw
Here is what overtile8 draws when called with various values of the tile parameter:
80181 upper right corner of widget box
103036 blackness
103376 full heart
103368 half-heart (empty on left side)
103380 empty heart
103388 half-heart (empty on right side)
A bit ugly, but making the if(fulltile) at the bottom of SW_GaugePiece::draw_piece look like this fixes it:
if(fulltile)
overtile16(dest,tile+offs,dx,dy,cset,0);
else
{
if( mtile + offs == 103368 ) // draw half-hearts that are empty on their right side, not left
overtile8(dest, 103388, dx, dy, cset, 0);
else
overtile8(dest, mtile + offs, dx, dy, cset, 0);
}
