I'm using BM 1.3.0b-3 and many other mods. The game crash while startup and CR told me it could be a BM issue. But I haven't got any idea which mod cause this crash. But once I downgrade the BM to 1.3.0a-1 it fixed.
Here's CR file.

That's caused by Mariculture. Disable it's BM integration.

So will you feedback this issue to Mariculture's author? Or let me do it?

Joshie is aware of this issue, so no need!
