launchtweaker hasn't been remapping refmap properly. I confirmed it was working on an older version of arch-loom, between then and the first 1.17 release, it broke.
does anyone really even need the baritone vanilla (json/launchtweaker) jar to work properly...

I'm working on getting this resolved on the arch-loom end as that'll be least painful for me :)

Some information

Operating system: n/a
Java version: 16+
Minecraft version: 1.17+
Baritone version: 1.7+
Other mods (if used): n/a

Exception, error or logs

n/a

How to reproduce

n/a

Final checklist

• [ X] I know how to properly use check boxes
• I have included the version of Minecraft I'm running, baritone's version and forge mods (if used).
• I have included logs, exceptions and / or steps to reproduce the issue.
• I have not used any OwO's or UwU's in this issue.

Yes, this is required for Impact.

resolved upstream, just need to update arch loom version and

loom {
    mixin {
        legacyRemapToNamespace = "official"
    }
}

to map to official... I'm lazy so I'm only going to fix it in my rework pr that moves things around even more, but I think that might need a tiny bit more work upstream for it to work there
