Mods, to deactivate

cargo_crates (0.9.2)

I made Cargo Crates and Checked this

Dreadgeworks with Cargo crates work fine
Dreadgepack with Cargo crates, also works fine

I am checking further, but are you running some other mods?

Yes, 431 Mods :-)

Then i need to know which one crashes with crates in order to fix it. It was not one pointed by you previously
