world scanner crashes in `spectrum:deeper_down` due to deeper down generating below y=-64
the spectrum deeper down generates between y=-64 and y=-320 which causes world scanner assertion to fail

I'm getting this same crash even with only trying to generate for the overworld

Hmm, I don't think it would be a good idea to add the export of levels below y=-64 since JER doesn't support it anyway. I didn't realise some mods changed this limit though, I'll change the assertion to a warning that levels below y=-64 will be cut.
@ArticulatedDrunk I'm assuming this is modded too, and your overworld extends below y=-64?
after modifying so I made a patch patch.diff.txt (not gonna pr this since it is very opnionated and is overall bad)
but after making a Y-Level override for spectrum deeper down
{
"spectrum:deeper_down": [-320,-64]
}
the range is now from -256 -> 0 but as I mention in https://github.com/way2muchnoise/JustEnoughResources/issues/468 it is unable to load the generated json.
world-gen.json
which the generated json from my patched version (after filtering for block ids containing ore)
Since v0.3.4 RegionScanner will now ignore the blocks below the depth limit instead of panicking. So scanning a dimension like Deeper Down that's entirely below the depth limit just produces no entries. Can't really do much else unless JER starts supporting such worlds, though. I'd still like to know what can cause the overworld to have the wrong depth, though.

A lot of the levels in your world-gen.json are negative, which is likely why JER refuses to load it. If you want to get this to work, you should have your overrides modify offset - so for that dimension, y=-250 should get stored as 70. The idea of the JER format is that all the levels in the world-gen.json file are always nonnegative (and JER, when loading it, will subtract the offset from them). If you do that, JER will probably load the file successfully, and the the plot will just be shifted right by 256 blocks compared to reality.
yep that works. aside from the y-values being wrong it works I may just PR this
patch.diff.txt heres the diff. makes it so y-override-json takes a json in the format of
{
"dim": y-offset-override
}

I'm pretty sure it doesn't. We ended up making a file by using the previous release but apparently jer doesn't even support ores on 1.20.1 so it's overall kinda pointless.

It does - I've been using JER on 1.20.1 with world-gen.json generated by RegionScanner without issues (though I haven't had any dimensions that go beneath -64).
Fixed a while ago when the assertion was changed to a warning, so I'm closing this.
