A few more point of consideration:
1.) The only way to check if this is an issue caused by a
version conflict within the save-state is to begin a new, standard game using the latest version 1.31 (1.32 on PS4). There are simply too many issues with "backwards compatibility" in that regard, so not all bugs can be
retroactively addressed. For several issues, the retroactive "fix" could or would break other, much more vital game mechanics. However, these issues should be addressed by beginning a new game. (I know that's really annoying for people that have hours and hours invested in a single playthrough, but these should only be minor issues. The Main Quest and the vast majority of side quests should still be able to be completed.)
2.) Any mods that affect
fast-travel, change how
experience works, or allow you to
bypass certain parts of the game (like using console commands) can trigger a domino effect in the quest scripts. A lot of players that hit walls in progress, find missing / odd journal entries, missing characters, missing map markers, etc. have used one or more of these mods at some point during their playthrough. If you have used any of these things, there may not be much to do at this point except reload to a save before you first installed the mod and play from there.
3.)
NG+ has probably seen all of the support it's going to see. It was never intended to be a part of the game, but it was introduced in response to player request. It stretches parts of the engine into places it was never meant to go. If an issue first appears in NG+, and any of point 1.) or 2.) above is also true...it's likely the end of the line.
If you have never used mods and are playing either a Standard Game or NG+, you can always feel free to send a saved game with the issue into
CDPR Support. They may be able to edit the save to get you past the hurdle. Just be aware that modded games are often beyond help. Since a few players seem to be encountering the same issue with the
The Devil by the Well, it might be helpful to send these reports in.
