Playing 1.54 beta and the distribution of fiefs seems to be wrong.
After every clan has at least 1 fief, the game starts favoring 1-3 clans over every other clan.
I've experienced this also in 1.53 in my playthrough where I was the ruler, where I wasn't given the option to give fiefs to others but a select few and from those it cost vast amounts of influence to give any but the same clan each time (Garros).
Currently playing 1.54 beta and the problem persists to extent where Derthert himself has only 3 fiefs but has given 4 fiefs in a row to Berican dey Rothad who now has 5 where others mostly have 2 tops, except Derthert who has the forementioned three fiefs.
Edit: Found a wanderer called Nortos with two-handed swords. He's 69 years old and has mostly just errors as dialogue. Sadly I didn't have any room for new companions so I couldn't investigate further.
