Console player- there a quests that cant be completed if done in a certain order such as finding the body before talking to wife at heartwood mill or rjorns drum

Is there a link of a list that says dont do until this?

rule of thumb.

If its a dead named npc. Don't loot their inventory.

If its a named weapon or unique looking item or book, don't take it.

Just remember where you saw them and when you get the quest your all set.

I don't know of a list, just what I have learned through experience.
