The bug
Sand and gravel used to generate in swamps in 1.6. In 1.7 and onwards, that no longer works. However, clay still generates.

Nope, It was deemded invalid by a helper back when it did not specify newer versions then 1.7 (which we don't take bug reports for) and then resolved by me.
I'm reopening now, as this issue seem to affect newer versions as well.
OK. But these sandless and "gravel-less" swamps could be kept as a separate biome (sandless swamp or something like that). Rarer, but it would still exist.
Is this invalid because it is intended?
