[2020] [Bug/Glitch]Persistent residence tiers locked after game load

Hey Takingsides, sorry to hear this and thanks for posting about it in the forums.

As you have enabled the new DLC on your current save, could you try verifying your game files first as this can often fix a multitude of problems and synch problems with the game -

Next if this doesnt not fix this issue in game and unlock the tiers, are you able to load up a previous manual or autosave that was saved before you enabled the new DLC as a test, then enable the DLC when prompted and see if the issue repeats itself?
