Couple days later and twenty or so reinstalls wiser I can definitely see where I went way wrong here.
Anyways, I got things running smoothly and about as proper as I can (definitely some strange avatar glitches but that's about it as far as I can tell.)
After delving into the big world rabbit hole, I finally found that... it seems broken? Hard for me to tell if I am doing everything right much of the time.
Anyways, I was unable to get the big world installer to put the bp-worldmap and infinity animations stuff in a proper order to install, so it would always come back with errors. I had to eventually manually install all the mods I wanted, putting the animations and map right after g3fix. Additionally, one of the animation rar's (I think the IWD one) had the same names as another content rar, so I had to rename all of these for all the content to unzip properly. (yep, remembered to select no path and everything )
So at last, re ordering things manually seemed to work.
Couple last things I was curious about.
I put BP second to last then g3 tweaks and then general biffed.
1) Does that seem good?
2) Some files were too large for weidu to biff (I guess the max size is ~16.5mb) so in order for this program to work, I had to go into the override file and temporarily delete(saved them for restore in recycle) all files over that limit, ran the program successfully and then restored all the files that were too large. Is this likely going to affect things? And is there any way I can biff these larger files?
3) Anyone know how to fix Edwin's right panel avatar being a question mark?
edit: and is it ok to put scsii or tactics mod on top of BP? Which is better for multi-mod installs?
Meh. Doubt anyone will respond to me, but it is worth a shot!
