Using Solidworks 2015 with EPDM 2015 (before) and EPDM 2016 (now). Same issue.
When an assembly drawing has multiple references (usually for views of the assy and views of some individual parts, see below)
the drawing will not get automatically checked in/out along with the assembly. I've seen this problem pop up a few times consistently and it seems to go away when the drawing only references one file. Is there a fix (other than polluting the assembly with needless configurations to get individual part views)?
