Problem with the fire fields of the campfires

[Albert34567]

Hi, i started botting port hope swamp trolls, but my char goes trought the campfires, getting burned. In the cavebot settings i put fields: walk around and furnitures: walk around but my char is still walking over the fire. The same if i put walk never :/
Any macro or something to repair this? (sorry for the bad english, and thanks for helping)
