Transcendence

I was recently playing a non-modded game in the Wolfen and I got the Aurochs Rescue mission. Things went fine until we got to the rogue base and then the Aurochs started circling this spot in space. I had already cleared the rogues, but the thing refused to dock.

Destroy the base.

Happens, just wipe out the rouges and wait. Base comes destroyed, you just need to wait until the Aurouch decides to go on.
