Concerning the AI: Well, it's a completely new one.
I basically rebuild everything from scratch and tried to made the AI act as close to a human as possible.
Short notes:
- less alliances, no huge blocks which last forever
- Naval invasions working.
- Better allocation of troops, not only on one frontier.
- Hopefully smarter invasion choices.
- Somewhat active rebels.
- Reworked global standing. (it actually has a purpose now)
- Reworked faction standings
- Better Faction-Balance
There are some bugs with stuck armies in foreign territories after a crusade, some issues with reinforcements being put to far away to actually reinforce armies, or factions like england or the almoravids having problems holding both sides of their empire, but thats it I guess..
