Can confirm that I have not been able to get mantling to work after the update - ON MY PARKOUR MAP. So incredibly frustrating! I’ve rolled back to an older version for now.
Someone suggested replacing the IslandSettings but that didn’t fix. Also can confirm that during uefn testing everything works fine but after publishing the mantling is gone. I wish I found this post sooner. I’ve spend the better part the day trying to troubleshoot this bug.
Just did a quick test and it does seem like after the player gets eliminated the mantling starts working. Hoping this can be fixed soon.
