Vanilla categories have a "The stack count must be 1" requirement, but Dark Matter works around it by adding stacks to the underlying set directly, this works correctly on Fabric, since no additional verification is done on the contents of item groups.
~In theory, this can be fixed by @ModifyArging the lambda or @Redirectinging stack.getCount(), but I wonder if anything else relies on this check.~ Actually looked into this. This would require directly copying the impl as-is from Fabric.

Additional context
Vanilla categories have a "The stack count must be 1" requirement, but Dark Matter works around it by adding stacks to the underlying set directly, this works correctly on Fabric, since no additional verification is done on the contents of item groups.
But, for some reason, Forge decided to add additional verification to item group entries.
