Reproduction
Have two contenttypes with a relation between the two
Have content for both types, with said relation used
Remove the related content from one of the content entries, and attempt to save
Receive an error
Bug summary
The problem lies in the $newRelations collection still having the removed relation in its items; when doing the "re-add new relations" bit after the remove, it'll try to look up the related Content items for that relations, which will fail because they've already been nulled. The fix is to explicitly remove the relation from the $newRelations collection.
