small vassalage mechanics changes:
- added rest of the norscan tribes to the vassalage mechanics (now all of them will be vassalized during second invasion)
- added 3 existing chaos-themed rogue armies that randomly spawn around the world to the vassalage mechanics

- reupload of yesterday's fixes because steam decided to not include them in previous version...

- fix for books of nagash panel having invisible icons

- added new SFO effect bundles for chaos legendary lords and factions

Lots of changes and fixes that hopefully will provide better experience with Chaos Invasion:

- workaround for base game bug that causes chaos armies getting stuck in encampment/raiding mode:
- reintroduced chaos subfactions that are available in Vortex campaign: Servants of Chaos, Chaos Puppets, Vessels of Chaos
- with only Warriors of Chaos faction, with higher number of armies from this mod, their faction easliy reached some kind of hardcoded army cap (~60 armies) => now with subfactions available this limit should never be reached, and that annoying bug should not happen anymore
- Servants of Chaos spawn in Naggaroth near Palace of Princes, Chaos Puppets spawn in the sea southwest from Ulthuan, while Vessels of Chaos spawn in the ocean between southern Lustria and Araby
- all those factions spawn with Warriors of Chaos and Warherd of Chaos both in the first and second invasion
- Warherd of Chaos armies amount now scales according to invasion difficulty
- new 3 subfactions armies amount also scales according to invasion difficulty
- no changes for Bjornlings, they spawn only in second invasion => it's mainly because this game has some kind of hardcoded limit for war declarations per turn, and with Bjornlings added to the first invasion it would be exceeded resulting in Bjornlings being at peace with everyone by default

- fixed a rare base game bug that stopped Chaos Invasion from starting (it was basically a random % to start it and if you had really bad luck it didn't start at all during only one-turn window of opportunity)

- reintroduced old mechanics that made all Beastmen, some Norscans and all Chaos subfactions vassals to Warriors of Chaos
- that way they'll never have war with each other and always have war on everyone else
- vassalage happens only in second invasion as that's when Archaon spawns, and it made sense to me
- vassalage obviously doesn't happen if player plays Beastmen or Norsca or Chaos

- new game is required to experience all those changes

Updated for new SFO patch - The Last Kiss. No further balance changes atm.

Updated for new SFO patch - The Great Plan. No further balance changes atm.

- removed the most stupid mechanics that made all Chaos armies disappear if Archaon, Kholek and Sigvald are dead/wounded at the same time
- now if Archaon, Kholek and Sigvald are dead/wounded, campaign objective 'defeat chaos lords' is still completed, but all remaining armies & agents from Warriors of Chaos faction stay on the map and fight on
- Bjornlings and Warherd of Chaos were not changed, as they stayed on the map anyway

- added 2 new spawn points:
- 1 for Warriors of Chaos at the northern edge of the map, north-east of Winter Pyre
- 1 for Bjornlings in the ocean south of Malus' start point (Dragon Isles)

- campaign objective fix

Updated for new SFO patch - The Sundering. No further balance changes atm.
