When I light a tree on fire to get rid of it quicker, some of the fire is invisible and NEVER stops burning. No matter what me and my friends do, we can't put the fire out, and it constantly makes the burning noise and sets us on fire.

When you light a tree on fire, after putting it out, fire turns invisible and NEVER stops burning. It burns eternally, and sets us on fire randomly near it. I've tried constantly to put it out by locating where is sets me on fire, but it never works.
