Just a quick update to fix some bugs.

One of Otomo's generals had 2 loyalty instead or 3. This had been increased to 3.

Uesagi didn't have any units in 2 of their 3 settlements. I've now added some units to their new settlements.

I was also able to draw a few more region boundaries onto the diplomacy menu.

I've added the following 17 new regions:
Goto islands, Tsushima islands, South Hyuga, Tachibana, Uwa, Nakamura, Agawa, North Omi, Nagashima, Osaka, West Echigo, Koga, Chiisagata, Kawanakajima, Osato, North Musashi, South Chikuzen.

Added the following 12 new factions:
Goto, So, Masuda, Asakura, Sanada, Ichijo, Kyosuke, Tachibana, Motoyama, Rokkaku, and Ryuzoji.

I've also fixed the bug that let characters walk over mountains.

Good news I was able to figure out why the new regions weren't working; the new rigid_spline borders I made contained and error, which prevented the official tools making a new startpos.

So the new regions Data, Hamadori, and Iwaki now work correctly. I've also added the new factions Soma and Iwaki.

Uploaded a new version that contains the new regions Sannohe and Oshima. It also contains the new factions Ando, Oura, and Matsumae.

Made the first version of this mod. It has the new regions Chikugo and Izumi.
