Unique Map Bug

I had some Unique Maps (2 Untainted Paradise and 2 Castaway Maps) bookmarked for later. After running other maps throughout the day with a duo, I noticed that before logging off 3 of those 4 maps had changed completely. 1 Untainted to a Merchant Map, 1 Untainted to a normal Wayward Isle (0 extra mods), and a Castaway to a 0 mod Crimson Shores. I haven't seen or heard of anything of the sorts happening and neither has anyone in my Guild. Kind of cheeks but it is what it is.

This happened to me today. A Moment of Zen became a Caldera and a Fractured Lake became a cliffside.

Same here. Thought I was hallucinating. I had Untainted Paradise and planned to run it today but it got changed to a Cliffside map :(

Happened to me as well. I noticed my moment of zen became a normal cliffside map while the castaway i was juicing with towers became a normal rugosa map today.

edit: checked previously done maps and also noticed that the path around my done jade isles totally changed while a previously completed normal node became a completed moment of zen
