Okay. Went back the nightly builds and tried rolling back a couple. I chose one from 2015 02 02. Merged it into my nightly folder overwriting as I went. Merged in the Soldier Diaries Nightly build as well.
Loaded early save, it worked like before. Loaded the next one that normally failed, and Behold! It loads! Woot. Ok, lets try my current save: Crash to Desktop, but thats ok. The LOG is griping that the terrain doesn't exist! All I have to do is renable my mods, and (crosses fingers), I should be good to go!
I honestly don't know if it was the 02 08 build, or just me messing up. Probably the latter, because I couldn't get the new legacy to work either. XD
Derp. Just the vanilla nightly build loads fine, but the soldier diaries executable doesn't work right. still having problems with it.
Edit: Sup's Nightly is like 7 MB, and the Diaries Nightly is 2.9. Is that because the .dll's are included in Sups?
