I'm sure I'm posting this on the right website. As I have posted bugs on this same site before, and they have never told me it was the wrong site.
My mistake, this is a biome after all! I just looked it up and it turns out that they really did add it. That's weird because I have never seen the biome on my own before. No worries, it is working as intended as I can see. Thanks for trying to help ;D
I don't think this is a biome, because the mod would have told me it was instead of asking for the seed. But I may be mistaken, I'm launching 16w15a now to load up some more worlds to see if they have that many flowers.
My apologies as I looked for "Minecraft" in the versions list, and I couldn't find it. All I saw was the launcher version, and I clicked it thinking it was the game itself. All the dropdown box had, was "released versions" - The Launcher, and "Future Versions", - future 1.7 and there was no option for "Minecraft" Thanks for the help.
