Meneth, a couple of things I noticed while doing the merges for the PB-compatible version that in the landed_titles, for e_scandinavia and k_finnland, the culture group required for formation is the in-existent "germanic" instead of the correct "north_germanic". I assume this was an accident while you attempted to remove all traces of norther_german.
Additionally, in my Hormuz mod I didn't give the patrician families any city holdings like the vanilla patricians, and while this isn't a serious bug per se it does put Hormuz at a severe disadvantage (among other things). I'm in the process of fixing that right now, so I'll upload you the changed histories for the new city holdings later today (so you don't have to re-merge with the updated Hormuz mod).
