It's NOT a glitch. It's a technique that allows the in-game matchmaking more time to find an occupied instance rather than having to create a new one for you because people like to sprint the whole way to the forge. Same thing worked in Court of Oryx. In your case, it may just be that not many are patrolling the plaguelands AND are in the Forge section in your area.

It's not a glitch. It's a way to allow matchmaking more time to do its thing.

Can confirm still working. Are you walking in from the door? Try crouch walking. Otherwise try going down to the warrens (water area below the forge) and walk back up, normal jumps unless needed.
