The Fae Vault contains a Defend objective that spawned all of its enemies when I arrived, not when the machine was completed. The extraction machine cannot finish its extraction, and stalls out indefinitely.
Edit: I completed the Vault at Champion difficulty successfully, but at Balanced, this encounter always spawns for me and never works as intended. The Defense encounter always has enemies spawned before I get there, starting the objective never spawns further enemies, and the objective never completes.
