Thanks for an awesome mod.

I am having an issue with compacting drawers - they do not render items on the face of the drawer; items cannot be removed from the drawers; shift+rclick shows an empty inventory for drawers.
This is similar to what is described in #issue 545, but I am adding it here for SD 5.3.3; also, I do not have ExU2 on my server.
Here are some images:

oops. images did not get attached...

Are you talking about only upgrade items? Since both those pictures do show items in the drawer.
