Untainted Paradise maps just disappeared

Over my end-game experience I have been saving my Untainted Paradise maps for when I need am on the cusp of levelling up. I had four saved yesterday with bookmark pins on each of them to help me find them. I logged on today and all four are regular maps.



It seems my unique maps may have been refreshed? I have also noticed 2-3 castaway maps that weren't there before also.

same happened to me, had an area bookmarked with 4 vaults and then other area with 2 untainted paradise and they are all gone - replaced with normal maps
