Trees(and everything else)=/= Netherrack!!!!

Okay, so I'm trying to figure out how to make fires extinguish after so long. I have Creeperheal and WorldGuard. I disabled fire spread and fire damage, but when I light something with flint and steel, it burns FOREVER!! How can I make it so the fires eventually go out?

 

I'm pretty sure if it's not working in-game try console or in the configuration for WorldGuard.

Code:

disable-all-fire-spread: false
    disable-fire-spread-blocks: []
Is two commands, that disables the spread,

ignition:
    block-tnt: false
    block-tnt-block-damage: false
    block-lighter: false
Is the line for ignition.

I'm pretty sure
block-lighter: false

is also another command. So if that is set to true I believe it disables it, try it out.

 

You could try disabling Flint and Steel... other than that I don't know. It does it on my server too. I don't think it's something that can be changed.
