I am doing LW S4 and upto 'Long Live the Lich'. I am trying to complete Guns, Germs, and Steel but after burning the barrel I cannot talk to Doctor Tasin. The green 'star' is over the doorway, and the Doctor Tasin name is shown under the 'star', but I cannot get any interaction! Another player was able to talk to the doc while I was there.
Is there anyway to reset the situation? Anyway at all the rectify my problem??
All advice appreciated thank you.
