I just took Pelatus C-12, got the "station has been conquered, Faille Corvelle now controls it" message, selected the key, etc. but the turrets are still firing on me. I checked the IFF on the key, and I've used this key in the past with no issues.

Gonna be hard to build tridents like this...

EDIT: Issue found. The docking and IFF on the user key were off.

Faille.

The user keys are always set with IFF/CanDock off by default. Reported it years ago :(

Aye that is still a bug. And a pain in the ass too.
