Multiple users are reporting a crash occurring when attempting to compile a PBB in L6. Please see this thread (most of it) for clarification. https://community.logos.com/forums/t/117147.aspx
I am using Logos 6.7 Beta 1, and although the file compiled fine with no crash, I am experiencing an endless sync issue.
EDIT/ADDITIONAL: I removed the PBB and the endless sync issue went away, however, the crash problem remains for other users.
