Ok so I'm at the point to update a map marker via quest alias, now this is how I setted up the whole thing:

-First I created a Reference Alias for my marker setting it to Finding Match Reference with two conditions one is GetIsId as Map Marker =1
and another GetIsEditorAlias with a location alias I have already created.

-The Location alias points to a location I've created for just that marker.

-So the last thing I do is to put a line of code on the quest stage which is:

Alias_*my alias marker name*.GetReference().AddToMap()

PS: I also point the quest target to the map marker, tried also with other objects to no avail.

Everything compiles goodd and all, but once I trigger the quest stage by talking with a guy, it does nothing, it update the quest journal but not the map marker.

I tried also to point the marker alias as force reference directly to the map marker, even if I wouldn't use it because of the persistence reference written on the save game it still doesn't work.

Most probably I'm missing something stupid and would like to know from you guys what may be.

Bump

Did you write the function in the script SetObjectiveDisplayed for display target on the map?

yes, already did.
