I'm sitting here with tons of mods from top to bottom of the load order on the FAQ, including four other field mods, all working, on & off with Satsuki's on & off respectfully.
I have nothing in my texture folder, ever, with everything activated, it doesn't work like that. The texture folder is there to build your own stuff from everything I've gathered.
Again, last time I got 7th heaven working, everything but field maps worked, I had to re-install after cleaning the registry, to get 2D field maps functional.
It might be your issue, it might not, but it's possible.
However, the Reunion I do not use, so I have no idea if there might be a conflict there, either, as that's why I didn't use it, because they are still building it and NOT updating it for fixes right now..
Also, I never use Tweaks & Cheats, or Difficulty & Story either, so no idea on those and compatibility, either.
