Quest Complete flag - 2.5.3.41812 [TBC classic]

That's essentially what I attempted doing.. and maybe got ~ 1/3 to 1/2 of the way you did!
Still a tad confused by it all, but I'll definitely take a peek and try to hack away at what you kindly shared <3

All of this is useful if you are OOP and just wanna determine quest is completed using only memory reading.
But since quest cache might not have the entry for your quest, you might want to have a offline quest Database for that and most likely only ObjectiveInfo and QuestFlags for each quest is needed.
Good news is that if you can determine if quest is completed for majority of quests and objectives. The only method I did not looked atm is 'PlayerFactionReputation'

Just click on variable and press n in IDA and rename it to whatever you want.

If you manually change the name of each variable, what about the next release...

You usually don't wanna analyze every build. Just keep using one as a reference until things change drastically.
for new builds just dump offsets you need. Anyway, I am not IDA guru but you might be able to write plugins/scripts to do that for you if you want.
