I've checked and nothing but UIO overwrites DarnUI in MO. I'm going to be uninstalling and reinstalling that whole UI section on the F&L guide to see if that does any good. I assume it has something to do with this? I disabled DarnUI by itself and it crashed even harder. The DarnUI Vault Guy/Pip Boy logo isn't appearing at the bottom left corner of the screen when you first load.my game crashes right before the actual menu items pop up on the main menu. However, while troubleshooting, I reverted my game to only the F&L mods and it STILL crashed - which is when I noticed something: After finishing the F&L guide, I added a few mods I personally enjoy, and that is when I started crashing. Everything worked fine and I launched the game periodically to make sure it wasn't crashing, and it wasn't.
This isn't my first time around the block by far, but I am rather puzzled by this bug I am getting. I followed the F&L guide to a tee for a new NV playthrough.
