This mod is all about putting out fires. Eventually it will do so in a vanilla friendly sort of way, but currently it is in alpha.
The roadmap is to add NPCs that spawn in, put the fire out, and replace any burnt blocks for free.
My inspiration for this mod is the old Builder addon for Citizens, which would spawn in a NPC, and build a schematic block by block.
Currently this mod only restores the burnt blocks. it is up for ease of testing amongst devs and beta-testers. Updates Will Come.
