Sorry for the late reply, got sidetracked. Some side quests don't have specific quest markers but depend on the player looking for clues or objects around the area the quest was gained in. We have added some quest markers to side quests that seemed unfair to the player, so if you have any specific exampled that you have encountered, we can have a look at them.

This is so bloody stupid. Every quest should have a quest marker. Or at least make it an option. If some people like the frustration and aggravation, then let them turn off the markers.

Well the game is complete now so they will not be updating that. You can always use the Dysmantle wiki for help with a quest or even Discord if you have lost your way.

Or dysmatle the entire map. You will come to the sidequests along this :)
