I've been trying to make my own faction, and I followed a tutorial(Will link below), but when I get into game it doesn't show up in single player, in multiplayer it does, but it shows the Faction Leader as Tyrion, and the game crashes on loading screen. .-. I also noticed if i try to do a custom battle it also crashes before loading. I followed every step, and tried 3 seperate times just to be sure I wasnt missing anything, and I'm not sure if maybe the tutorial I followed is not compatible with War hammer 2 or maybe its missing a step or two? >-< Any help would be really appreciated!!! <3

Here is the link to the tutorial: https://www.youtube.com/watch?v=gLhtQ-DVSDc&t=1158s&ab_channel=MagnarChannel

Alternatively here are the tables it had me edit:
factions
faction_uniform_colours
faction_to_faction_groups_junctions
faction_political_parties_junctions
faction_banners
commander_unit_permissions
names(This one I did on my own to get a custom name for my faction leader)
political_parties
start_pos_character_to_settlements
start_pos_character_traits
start_pos_characters
start_pos_diplomacy
start_pos_factions
start_pos_land_units
start_pos_past_events
start_pos_regions
units_to_exclusive_faction_permissions
