Hi
I get "circular dependency detected - reference entity depending on corridor result" when adding a widening geometry through Pont Control to a corridor.
I am using Realesae 2 Update 7 - Version 10.07.01.32

Solved for me, cannot have station limits snapping to anything on the template/ corridor. Try to set station limits a bit further than what you need, and do not snap them to anything.
