Something i've noticed while testing the new 1.6.0 update of BetterEnd Forge on my modpack. I've also added a modlist. I don't have mods installed that fundamentally change the way Minecraft terrain is generated nor do i have any other mod that adds biomes or changes terrain generation for the end. At least that's what i think. Maybe there's some mod in my modpack that breaks something for BetterEnd Forge? I have left all config options at default settings too. See images below:

Edit: I have completely dry Megalake Groves generating as well. Not quite visible in the screenshot but barely visible on the minimap in the top left corner, which is partially blocked by the debug info. (It's on the east side of the minimap.)

Fixed in b832733.

I also have this problem too, every mega lake I find is dry or is extremely tiny, like literally the size of a pond

Can confirm, this also makes menger sponges and end lilies very rare. Incidentally, the lake itself is actually a structure that spawns in the biome, perhaps, the generation is underweighted?
