Yes I did, that didn't help. I tried rolling back to U1 and that didn't help either.
Also: I tried to install a fresh Plex plugin and I get the following:
[EFAULT] Exception: CallError:[EFAULT] pkg error: - pkg-static: /var/db/pkg wrong user or group ownership (expected 0/0 versus actual 1000/0) Please check your network occured, destroyed plex_2.
I created a new jail from the web interface, indeed lots of things are owned by 1000:
