Cannot access Mt. Komorebi

I had TOOL in, but removing it didn't fix the problem. Now I'm playing with no mods at all and a new file. The old one still doesn't work even with repairing and everything done and without mods. Also the game worked fine with TOOL in it, prior to installing Snowy Escape, I've been testing platforms after the update with only a few select mods on (Twisted Mexi's build mods, including TOOL, Red Shelf and cmd center) and it worked just fine.
