Extinguishing fire on buildings

Anyone know how to do this?

I have 4 buildings in my map that should not be on fire no matter how much damage they take. I can't seem to figure out how to get rid of the flames. Any ideas?

Remove the mechanical classification?

There are specials ability "in fire" for each race. 'Afix'
Remove them for your buildings and they won't fire.

x -> first letter of the race name

So for human -> 'Afih'
orc -> 'Afio'
undead -> 'Afiu'
night elves -> 'Afin'

You can see them in the object editor if you use UMWSE (as a plugin of JNGP or an editor)

Awesome Troll-Brain, thanks.
I'm not using UWSE (not yet anyway) but I can easily use UnitRemoveAbility() to get the job done.

I made a typo UWSE instead of UMWSE.
There is also the ability "in fire" 'Afir', maybe for the other races, but i didn't try.

Just a thought, i dont think that neautral buildings burn at all... so try setting the race to neutral!
