Concorde HSI CRS bug non functional

[lukasw]

I have a problem using RadNav devices on the concorde. Sadly somehow i'm not able to use the OBS knob. The CRS needle just stays on the North position no matter the entered course. Tried all methods: Using the VOR/LOC REF Knob on the A/P Panel, Using the OBS on the bottom right on the HSI and also tried to input CRS via FMC. I only get the derivation but with the needle always pointing North.
You Cant even really use it like a CDI.

BTW the needle turns just fine in INS Mode.
