The lighting time is random and depends on your firemaking level, it can sometimes take a bit longer. Is there any way to force a fire to stay on a spot forever? Any way to reproduce that reliably? Random and sometimes are always words that make it difficult to fix bugs for me.

yea ive seen how it works when its fireing the log, but when its done that it just stand ups and stays in the same place , roughly ~5 seconds and then it moves and the fire comes.. this happens pretty often.. i cant make video myself because i start to lagg a lot when videoing for no reason so.. you need to either get the video from some1 else or try it urself.. this has nothing to do with fm lvl cause yea it sometimes is down there putting the log into fire but then when it stand ups and nothing happens? i dont think thats part of it. Then the forever fire there isnt really way to reproduce it atleast i dont know one.. i just happens-- that fire which is in the pic i went to bank multiple times , meaning it wasnt near me and i couldnt see it but it still stayed there. Sometimes when "visual bugs" disappears your sight its not there again when you go there.
