Nezun.Skyfire

I've spent the last several weeks off and on trying to do Isolation Vaults on Deimos, and the objectives refuse to spawn after going out into the fields. Today was the first day I've managed to actually get into the vaults for two missions in a row, only for the next several attempts to fail. Returning to the Necralist states that the bounty didn't even start. I've been away for several years and this is still an issue? This is hard locking me from getting a Necramech to start New War. This is absolutely unacceptable.
