Hello,
I encountered probably a bug by accident.
The two variations of the Thyssen Krupp Low Level 3 tunnel do not work.
If you have them "installed" at an airport, you get the error message, that no jetways could operate at this position. And opening the SODE menu says that there are no triggerable objects within 6 miles or so.
Replacing these Low Level Airstairs with any others works at it should.
Is this intended or is this a bug?
many thanks!
