ANSWER DAY - Featurelines used as Corridor Baselines Disappearing

[fcernst]

Hi Dave/Tim-

Can you please answer to this one specifically. I just had another featureline suddenly disappear about ten minutes ago this morning.

I have provided samples of this behavior to Support since 2017. 

When will the problem of Featurelines used as Corridor Baselines suddenly disappearing be formally addressed with an official announcement from Autodesk?

I have now lost my entire 9 acre parking lot Corridor... That was 4 days worth of work.

This drawing is only 4 days old and was created from the stock NCS template.

This is an insidious bug and is totally unacceptable.
