Not sure if this is of interest, but I created a spreadsheet of quests that can accidentally be missed and unable to be gotten later. One of those 'if you do this quest then that other quest over there isn't available' There are some either or quests of course, which aren't technically missable.
My goal is to try and do all quests in game, even the bread crumb quests. Some quests require creative planning. Like Grahwood's Trouble at the Tree...I had to get the quest Great Tree...do Unsafe Haven...delete Great Tree, get Trouble at the Tree then go back to Audidron to reget Great Tree so I can do both quests. I find alot of fun in 'working things' so I can do that.
These are my notes and affected quests taken along the way.
If you like torture, feel free to check it out.
If you find anything I need to add, do let me know! Endoc's completed journal add on is very helpful!
