Resource Pack on 1.21.5 branch backport overlays don't load #1257
Description
Creating this so we don't lose track of it.
Currently, with the 1.21.5+ branch the built resource pack contains erroneous overlay entries in pack.mcmeta, which are causing all overlays to fail loading, resulting in none of the backports functioning.
This is caused by something in our Beet pipeline or maybe this is a beet / mecha issue? we're not sure. @BPR02 and @SpecialBuilder32 did some digging around new years, but there has not been any updates yet.
