Well there is the anti fire spread plugin where wood materials are protected from fire but, I wonder if its possible to make a plugin where ice is not melted from glowstone/torches like a anti melt plugin. That would help so much to build ice structure that you want well lit but don't want to melt. It can be toggled to on and off like the anti fire spread plugin. So if someone can look into this and see if such a plugin is possible. It would be greatly appreciated.
