no other mods

When you launch a game, it brings up the Narrator screen instead of the Start Game screen.

I'm guessing you turned this on because someone onb your end is visually impaired, but as I'm building a modpack and have to go in and out many many times, this was driving me crazy and it took me the better part of an hour to find which mod was causing it.

Please consider turning this off as a feature, or make it so that it has a config file that turns it off.

This isn't an intended feature.

Something is an issue here.

This issue extended to pretty much all options from what I've seen, huge issue that'll be fixed in 2.2.0.

2.1.0 was broken in multiple areas that I just didn't test. Apologies for the inconveniences

I'd suggest downgrading to 2.0.x for now, that update was a lot more stable than 2.1.0. At least until 2.2.0 releases.
