I'ts all said in the title.I had to make plates 250 blocks in the sky for them not to lose their helmets but then normal mobs didn't burn. That is a big problem not just for me but for other mapmakers too. I know it is hard to fix becose of the Undead/non-Undead but please fix it.
It will also fix Zombie Pigman, Wither Skeletons and Husks not to burn at day in the OverWorld
