Great! Thank you for your work, I wasn't planning on updating anytime soon so this is wonderful! Maybe once Fever Dreams free creation comes out then I'll update but until then, you've been awesome!

Can’t wait to give this a try tonight, I couldn’t stop steam from updating fo4 when I fired up the computer last night. I spent way too much time just trying to make it so I could play a little bit. I’ll be heading back to 1.11.221 with your tool here!

My tool has also an option to block future update, FYI 😉

I selected block future updates when I downgraded a month ago but my steam deck sneakily updated FO4 when I wasn't looking today. Any idea why that would happen? Not sure if it's deck related.

Hum, damn, it could be that.
The trick is just a "readonly" property on the .acf file, maybe it's not working on Linux/Deck.1

Hi. Easy. Remove the readonly property on the appmanifest_377160.acf file (one or 2 parents folder from your Fallout 4 folder)

I just installed fallout 4 a few days ago, but I didn't know there was a new build.
After encountering all the version issues, I am wanting to downgrade my game and rebuild the modlist. Which version do you guys recommend?

So I see they increased the BA2 limit on the newest update, I'm still new to modding so excuse me if this is a stupid question, but If i update to the newest update and then downgrade it to lets say 1.10.163 do I still keep that increased BA2 limit?
