Remapping MC Jars throws ArrayOutOfBoundsException

The error Message. I looked at the code and noticed at
net.patchworkmc.patcher.mapping.Tsrg.readMappings(Tsrg.java:43) (the exact error line)
there is a assumption of a length 2 or more. if this is needed, then I would recommend having a try catch to throw a more descriptive error.

Got the same error.

If the developers need a output, here it is:

Hope you can help, this is an awesome project!

Can confirm, has happened to me too. Although perhaps a temporary solution would be to use patcher v0.3. (1.16.4 mods are internally compatible with 1.16.5, so it should work, i think) This happened to me on v0.4, now that I've seen you're using a pre-release snapshot of v0.5.

SRG changed their format and the mapping downloader for 1.16.5 is broke, not sure if we wanna hard code an older URL or what

You gonna make this download from the mcp config maven, because that wasn’t changed.
