Konnichiwa,
There is some really strange thing with Deep Caveworld. Every time I try to enter it (with enough points), the world won´t generate. The whole Minecraft is stuck then. If I kill it, then I will reappear just like I was before entering the deep cave.

Can you try to look into it, why deep caveworld is not generating at all?
It even do not write anything into console. If I try to stop server (log off in singleplayer) it won't stop unless I kill minecraft completely.
