If you haven't already done so, please take a moment to visit the AutoCAD & Vertical Application Bugtracker website. It's managed by a great guy named Ralph Sanchez. He's keeping a list of "known bugs" for AutoCAD products that have been submitted to Autodesk.
The website currently lists bugs for the following products:
AutoCAD Civil 3D
AutoCAD Land Desktop
AutoCAD Map 3D
If you know of any bugs in current AutoCAD or Vertical Applications that have already been submitted to Autodesk, just submit a bug report to the teXupport.net website for all others to see. If you know of a current "work-around" or solution for the problem, be sure to include that information with your bug report. I won't promise any miracles, but Ralph and his trusty band of hooligans may even be able to help you find a "work-around" or solution to the problem.
Ralph will review the submitted bugs to determine that he can duplicate the problem, but Ralph and this website are NOT to be used as your main source of tech support for problems with AutoCAD products. You should always communicate potential bugs directly to Autodesk. Or you can discuss them with your Autodesk reseller, mine is D|C|CADD, if you are current on your Autodesk subscription plan.
While you're browsing the site, review the Downloads Section of the website. This section contains some useful utilities such as "Lock All Viewports" and "Multiple Offset".
The website has an RSS feed so be sure and add this to your favorite RSS reader, such as SharpReader or NewsGator, so that you get updated with the latest reported bug info as it is added to the list.
