{+}A dyed leather horse armor looses its colours
{+}when "quick" equipped on horse
dye a leather horse armor
use the new "quick" equip on horse (click on the horse with the dyed armor)
leather horse armor is equipped, but it's the default one on the horse, without the dyes
Notes:
When taking back the leather horse armor from the equipped slot, the color does not re-appeared : the dyes are lost.
No bug when the dyed leather horse armor is equipped using the horse interface (the way before update).
