Problems creating pdf's from AutoCAD Civil 3d 2018 after upgrading to Acrobat 2019

Ever since we upgraded to Acrobat 2019, we have been having problems creating pdf's from AutoCAD Civil 3d 2018. Black/white pdf's appear to have colored linework on-screen while zoomed out but turn black/gray as you zoom in (the pdf's plot correct without color). Also, random linework in the pdf is broken/randomly jumbled - dashed lines appear as arrows.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Have you contacted Adobe Support?  Their support is usually pretty well versed in common support issues for which this might be one.

I will also add that having worked for a few device manufacturers that have experienced "Adobe Issues", I have had to load CutePDF on multiple occasions until a suitable resolution was handed down to us from Adobe Support for our installations of Adobe.

Hope that helps!
