[Minecraft 1.20.x] ++ Improved compatibility (technical: no longer uses overwrites) ~~ Reworked default spread mechanics (should behave about the same)
If you had this mod installed before I recommend going to your minecraft install directory > /configs/ and deleting the file named "firespread.json5", this will make sure the behavior of the fire is reasonable. Not doing this could result in very weak or very strong spreading.
