Sad to hear about this issue. I like the idea of Guided Games and I was hoping to use the feature somewhere down the line ( when Nightfalls lost the time limit and there was a Raid worth doing ) but this news puts me off ever using it. I'm not sure what Bungie recently did to the net code but I've been experiencing connection issues ever since Monday's maintenance, yesterday alone I was disconnected multiple times while I was in the middle of various activities. At the very least there should be a window of a few minutes where someone can rejoin an activity if they were disconnected.
