Hey guys, my friends and I have a server running the DF-Large map but for some reason the wandering survivor lady's questline is bugging out and we've been unable to find the second science lab as a result, my pal Dirt and I have spent around 30 hours in the wasteland and the irradiated zone searching and can't find anything so we're kinda stuck. Any ideas? I saw this thread was about playing on the pregen maps is why I mention it here since we're having problems with it. Thanks!
