Well good to know, then when I'll play it I'll make sure to check every "path detected" of URM in between scenes and there is where they usually trigger or not, you shouldn't miss any scene if you monitor them, in last case I'll monitor them all in the new chapter just in case.
Yep you can change the tag/variable in an earlier save or just change it on start of chapter 11 and skip with CTRL key already seen text, seems safer and probably you will get any scene you may think you have missed, also KN mentioned that there isn't any new scene on prior chapters so if you missed any scene is in chapter 11. Also I save in every meaningful choice and on start and end of updates, seems the reasonable thing to do when I usually use mods and also in games that are still in development.
If like KN said in a previous post that some variables were new but for sure there is still a trigger somewhere during the story and if the variable is in the default state then probably may not trigger some scene(s), just have to "remember" them and change accordingly

. But in the last resort I'll simply start a new game and CTRL skip the game but if I can avoid that even better.
