So, I tested it with my current development version (so there might be a difference to what you experienced with the released one). The Khazad vault BUG option does nothing, I'll remove it. The vault bar is displayed, though, on the top right. Same for adaptive and barbarian mistrust. Any chance you missed that?
With Khazad, I have no vault bar.
With Malakim's Varn, I have no Adaptive bar.
With Kuriotates' Cardith Lorda, I have no Adaptive bar.
With Grigori's Cassiel, I have no Adventurer Counter bar and no Adaptive bar.
With Charadon, I have no Barbarian bar.
With Clan of Embers, I have no Barbarian bar.
With all of them I have Technology/Research as top bar in the middle with Great General bar to the bottom left of that and Great Person bar to the bottom right of that. Although I can't read the bars anymore if I go to higher resolutions, I can tell they go to a single line at higher resolutions. I see no bars of any kind under the clock, turn counter, menu button or advisor buttons if that's what you mean as to where there should be bars. If I am playing on variable difficulty challenge or a scenario red text is displayed below that area on the top right, but I see no bars there. When I play as Kuriotates, then on the top left to the right of the research "slider" (which I've never understood that name since it has never slid just has +/- buttons, but I digress) I see the current/maximum cities in white. I also see the Maximum Cities shown on the Kuriotates' flag hover tooltip as usual, and the vault status tooltip when hovering over gold as Khazad, but I don't see any other place to look where the Barbarian or Adaptive trait information/progress can be seen in any fashion. Is it possible to see this information without bars somewhere? If so, then I can live with the loss of functionality as nothing else seems amiss. For the Adventurer Counter, that's a different story as I have no idea what's happening there without a point of reference.
I didn't even know the bars were supposed to be a thing until I was trying to play as Grigori for the first time and observing nowhere to see said Adventurer Counter. Recently going through the notes of changes and what's in the python scripts I then saw the bars' coding, but I didn't see a more recent emm_features.txt since 6.0.1 to check if something had changed even though I see these bars identified in the python MainInterface.py still there, not commented on and not removed or commented out. I see no other references to them at all in any other files, so I don't know if they're stand-alone there in MainInterface.py what else could be conflicting that would give no errors at all but just never display the bars. I do see references to the Adventurer Counter in the CustomFunctions.py and CvEventManager.py, but even if there were something amiss there (which there isn't as far as I can tell), I don't know why all the other bars would disappear without any error or hint anything is wrong. It's all terribly mysterious! (smile)
