Precursor Tablets not dropping - Traitors Passage & Trail of Chails bugged

So far, I have yet to see my 2nd precursor tablet while I'm running T13 corrupted rare maps the whole time. I know it is RNG-based, but this seems to be stretched too far. I have seen more divine drops then tablets, which is starting to frustrate me at this point.

I have seen some people complaining about the quests Traitors Passage and Trail of Chaos, that they are not able to proceed. I got the same issue right now too. Got my 3rd ascendency already, but the quests are still bugged.

Are the tablets locked behind these bugged quests? And if so, how can I complete these quests? I have run multiple Djinn's and Ultimatums succesfully, but the result is still the very same.
