...---this issue is occuring during my present Fighters Guild quest, the "Hist Tree"--- ...I'm in the basemant of the Blackwoods Hall in Leyawinn...was sent there to destroy the Hist Tree. Problem is, once I'm there I'm prompted onscreen that I must find a way to destroy the "alien machinery" used to extract the hisp in order to destroy the tree itself...and there's no further quest info, arrow, or directive whatsoever in my menu or from Orewyn in Chorrol who sent me on the quest in the first place...all I find are two loose pipe sections by the boiler which prove useless...I tried jamming the pump gears with them, but they just rattle and fade through them like a ghost...and when I approach the boiler and tanks, the activate option comes up, but with no result when I try... Is this a glitch, or am I missing something??? Any advise will be welcome.
