I had a modded world in Minecraft with Forge 1.17.1.
I updated a mod, which now needed the latest update of this version of Forge, so I downloaded it.
When I came back and tried to load my world again, now there was a "world errors in datapack prevented world from loading."
This wasn't here before, as everything had worked perfectly fine. All mods were 1.17.1 and all resources were as well.
I fiddled with it for a bit, even looking into the world datapcks inside the world editing, which for some reason shown that many were 'outdated' even though they were all stated to be 1.17.1.
I gave up after playing with it for a bit, and just deleted the world entirely hoping maybe it was an old saved log. That was not the case as even trying to make a new world brought up the same message. Any suggestions? I'm at a complete loss here.
