This is my current config, both the default and admin group and my user have the blueprintmanager.config permission and they do not get acces to any of the blueprints in the config file:

Try removing all .blueprint and it should work on player connect.

Even then it doesn't work

Apparently this config is invalid so it just resets it for some very dumb reason:

There are 4 dots where they should not be ;)

"wall.external.high.",
"pants.",
"jacket.snow.",
"explosive.satchel."

*edit: But the error indicates something different. I suggest removing the last } and add it back manually.

Turns out i indeed simply had to remove the last } and add it again for some odd reason
