I keep loosing Vertical profiles in ORD 2020R3. My work flow is as follows- I will draw the vertical profile by tracing my active terrain, (snapping to it I believe) I will complex it, set it active and move on, removing the active terrain, and everything looks great. I come back to that same vertical profile after some time and this is what my profile now looks like. Is this a bug or something I am doing, and not realizing it.
This has happened over 20+ times within the last few weeks and is becoming quite frustrating.
