There is a bug in 2.8x where saving with an active linked scene crashes on reload.
There isn't much to redo this error
In the attached file:
- Open link_dst.blend
- Switch the scene to Scene Link
- Save, Load (crash)
See P567 for the crash log, although Im not sure this points to the root cause.
From looking into this it seems readfile.c expects the view_layer pointer in the workspace to exist in the scene - which isn't the case when the scene is linked.
