I was trying to make a Minecraft x Doctor Who Modpack, and inside of the Modpack, I installed this Mod and many Dimensions Mods (because I also installed a TARDIS Refined so I have more dimensions to explore). When I checked other dimensions, I noticed that some Modded Dimensions spawned too many Weeping Angels or did not spawn at all. Here's what I found:

• Aether Mod: Over-run by Weeping Angels (350+ Entity)
• Deeper and Darker Mod: Over-run by Weeping Angels (500+ Entity)
• Blue Skies Mod: Both Everdawn and Everbright dimensions seem to not have any Weeping Angels
• Undergarden Mod: around 15-25 Weeping angels
• Ad Astra Mod: I've only checked a few places from this mod and it seems that they also don't have any Weeping Angels

You have a config to disable these biomes and change the numbers, Minecraft has horrible fragile spawns code
