I noticed the torches and decided to try it out. The 1st run went quite smooth (though I didnt succeed). The 2nd one I made it, perfectly fine. However on my 3d try the third torch was already lit but still showed the icon, thus preventing me from completing it once more. This is probably nothing big but I thought I’d mention it, since if this continues its an entire achievement category thats being blocked.
