Nothing comes up when adding a pod with the MJ module, or the AR202 case. I would post an output log, but there is nothing I can see related to MJ not showing up (no references to MJ once enter editor).
Just in case, here's a log of me checking a vessel in flight (MJ windows show up) and then going to VAB (no MJ windows): https://www.dropbox.com/s/9rvjb2jz7e2mvsd/108_noVAB_output_log.zip
It worked as of 106 with my current setup (I just rolled back to be sure); 107 does the break-VAB thing you fixed; and now there's 108.

It most likely come from the fact that time don't change in the VAB and my new caching algo use time ...
