Move your Mods folder to the Desktop and delete localthumbcache.package. Then test the game in a new save.
If it works now check for updates to your Mods and CC. Add it back a little at a time while testing until you have found all that are broken.
I have done this and have no mods or cc in my game but I still can’t unlock this milestone, the other ones worked fine it’s just climbing stairs that isn’t working
@RoyalRoses2019 If you tested on a folder with nothing else but the resource.cfg file it in and are still not getting the milestone, it's best to report it at the bug forum. There seem to be a few that don't trigger.
(one thread per milestone)
