When running an autolist, you're no longer getting the listing tag IDs such as MAIN A.1, MAIN A.2, MAIN A.3, etc show up on your drawing.  It only shows the original tag of MAIN A 

Same can be said for line tags #LN1.1, #LN1.2, etc

When starting the AutoLIST process, the message box shown below pops up.  The process "pretends" to continue through, but when HydraLIST opens, it's completely blank.

After running an Autolist, in HydraLIST and the LINES tab you have a listing tag ID called RM

Upon starting the Show 3D command (S3D) the drawing immediately switches to SE isometric, reports no errors but no 3D piping is visible.  Even newly drawn pipe won't elevate.

Drawing successfully elevated to 3D. No errors were found
