Farmin the bunker

Alright so I just killed the bunker, and it didn’t drop the bitch. So I exited to thousand cuts, saved and quit, came back in, and now the bunker isn’t respawning so that I can farm the bitch. Did this get patched or what?

No patch. You have to turn in the mission after killing him the first time then you can respawn him as many times as you want by either quit/continuing or exiting to 1000 cuts and reentering the bunker. So yes, you will have to make the run all the way through 1000 cuts to farm him again.
