Looks like I'm getting the following crash on world generation:

Pretty heavily modded setup, so it could potentially be an incompatibility.

Yeah I am getting the same crash.

I fixed the same crash in another spot, but I missed it somewhere else. I'm fixing it right now.

Fixed in 1.3.2...hopefully. It shouldn't be in any other places.

Yup, 1.3.2 looks like it fixed the problem for me. No crashes and some fantastic new features. Keep up the good work. I'm really, really enjoying the additions from this, especially when coupled with Dynamic Surroundings. It's like a brand new game.
