FlashFreeze

# FlashFreeze FlashFreeze lets you remove and add content- adding mods without dropping any blocks, entities or items.   You can use it to migrate to a newer version of Minecraft without waiting for That One Last Mod, or turn content mods on and off one by one to nail down that pesky bug. ## Usage  All unknown blocks, items and entities are presented as missing textures or as Source Engine ERROR models Once you turn the content mods back on, all the FlashFrozen™ content is defrosted 100% fresh!
