Sim only displaying generic aircraft during multiplayer

Hi everyone. Has anyone experienced an issue where only generic aircraft are being displayed during multiplayer? I have the correct settings in the traffic menu, AI and multiplayer selected to OFF. Was flying the other day with several DC3’s and I had the livery for them but I could only see a generic model. I had no issues before. I’m wondering SU 11 may have done something?

Try searching the forum there are several topics about this. Short version is it’s really buggy. Sometimes it works but mostly it doesn’t.
