So with WW 2.0 beta, it seems that there were some errors when trying to export my VMF with the displacements.
The first thing I did was use the same scene that exported before but had errors loading in Hammer and re-exported with WW 2.0. This produced an error and looking at the Maxscript listener it seems to be something with the materials. I tried to fix it by making a new material and just placing, clicking send to displacements but that didn't fix the issue.

Issue 2:
Thank you for reporting. I'm looking into this now. Can you send me an Archive of the scene before you started testing the WW2 changes so I can reproduce this?
