I own a server that I play in with some friends. I recently reset it after we had already gone through some time of inactivity and I'm currently exploring the world to see if everything's the way it should be, but as I'm mining, I'm noticing there aren't any fossil blocks at all. I went into creative mode, flew through the entire cave I'm in, and there are zero fossil blocks. I'm not sure what's causing this. Maybe one of the mods I have installed? I've played with this mod before with a lot of other mods, and fossil blocks still generated just fine.

This is my full list of mods:

-AppleSkin
-Better Animals Plus
-Better Burning
-Better Combat Rebirth
-Better Diving
-Better Placement
-Biomes o' Plenty (though the server isn't using Biomes o' Plenty generation)
-FoamFix
-F&A Revival
-Future MC
-GalactiCraft and 3 more addons for it
-MrCrayfish's Furniture Mod
-Macaw's Furniture
-Mining Goggles (Used this to look for Fossils just to make sure, found absolutely none)
-Ore Excavation
-Quark
-Scooty's Plants vs Zombies
-The Aether II
-The Erebus
-The Twilight Forest
-Tinkers Construct
-Tinkers' Tool Leveling
-VeinMiner
-Weather, Storms & Tornadoes
-YUNG's Better Caves (Majorly suspect, it could definitely be a world generation mod causing this, and this specifically changes the generation of caves.)

I really need some help. I want to make sure everything in the server is good before my friends play.
