Distant horizons / Oculus on Forge

I try to start my Forge modpack with DH + Oculus + Lazurite(Forge port of Indium)... but it sadly crashes and I can't get it to work.
Any idea?

Solution

okay I've found the issue mod!! FINALLY.
Its a mod called "Alex Caves" which is a really nice mod btw, but it somehow breaks Distance Horizons completly.
