ModPack: Direwolf20 V1.0.16 1.6.4
Mod & Version: Unkown
Pastebin link to crash log: No crash
Whats the bug? Normal world spawns in pre existing chunks no longer spawns badies at night. ( Squids still seem to spawn )
Can it be repeated? Unknown cause
Known Fix: Changing the mode to peaceful and back to normal fixed this. It looks like the issue is the mod pack update sets the game to peaceful mode but the options still show that it's on normal difficulty.
This is probably what I reported here: http://forum.feed-the-beast.com/threads/direwolf-20-1-6-4-public-beta.35476/page-76#post-574416
Setting it to peaceful despawned the hecates and let the world repopulate with normal mobs. Doubt that the hecates are any less broken afterward, though. Did you start this world in 1.0.16, or was it updated from a prior version?
