Area cursed with temporal chains/elemental weakness...

Never saw these before the most recent patch, but they're showing up a lot in my delirium infused waystones.

Not listed anywhere on the map location or on the waystone itself, and I'm not doing any additional corruption/suffix/prefix atlas points.

Where is this coming from?

The way the curses on waystones operate was changed in the latest patch.

"Endgame Waystone modifiers that applied curses to the area now instead periodically cast the respective curse on ground targeted areas, the same as the player casted skills."
