Bugged locations for Guild Trek
I dont think the locations are always the same but they do keep going bugged after a while. They work again after updates but it is rather annoying spending influence and time in it when you get lots of bugged locations.
Think out of 30 treks we had 15 bugged ones by now and last 2 had multiple locations.
This provided me early on with enough time for a screenshot:

The yellow markers dont pop up on multiple locations and standing on the location trying to just press the activation button wont help, and the trek will fail.
