Sorry to post in this old thread but it's not letting me start a new topic. Someone actually asked about the specific quest "finders keepers" but it never got answered. I have gone through the files in accordance with the instructions here, found the quest id (mq2002), and tried removing AND adding basically every combo of events there.... STILL nothing! I have an awful suspicion it's tied to the Griffin scavenger hunt chest that's in the same location as the bandits that you're supposed to kill to trigger the quest but I can't seem to figure out how to make that chest reset so... D:
I am so ocd about games like this-- i made a SPREADSHEET-- i did my internet research, seeing which quests could fail!-- but somehow finders keepers never made it on those lists and now i'm 120+ hours in, probably at least 30 hours if not more past the point where it would be fixable normally, and this is the only thing i've actually missed in this g.d. game! it's gonna drive me NUTS if i can't fix it. please, someone with technical know-how, share your wisdom...
It's possible that even manually editing the quest IDs via the console will not force the quest to complete. It's an extremely complex game, and depending on the literal millions of potential variables (which quests the player completed...how...when...in what order...at what level...where in the main arc...etc.) it's wholly possible the game may be in a situation where it cannot "complete" that quest. (Even if the player technically completes the quest, the numerical logic behind the actual game engine may make it impossible for the journal to be updated. Alternatively, the engine may prevent the quest from completing to avoid an exclusion that would break the playthrough in a more serious way. Or it's just a glitch. Hard to tell for sure.)
Honestly, TW3 is not a game that was designed to be "one-hundred percented". Unlike other open world games, like Far Cry, Assassin's Creed, GTA, etc., TW3 contains numerous quests and decisions that intentionally exclude other paths through the game. Meaning, if I have a choice between a.), b.), or c.) at a particular stage, I can only choose one. The other two, entire quest chains become unavailable to me for the remainder of that playthrough.
So, the only way to "see everything" is to play through multiple times. (And hell, I've played through almost 6 times, and during my last run I found two quests and a few encounters I had never come across before. I'm sure there are still things in Blood and Wine I haven't found.)
