> When using multiple cluster nodes, the node data stored in MongoDB can get corrupt. Unfortunately, there is no reproducible test case so far; we only have the corrupt data so far.
> It looks like the node was added by cluster node 1 in r142b9051a3e-0-1, then removed _twice_ by cluster node 2 in revisions r142b9064ef5-0-2 and r142b9064f10-0-2, then re-added by cluster node 1 in revision r142b9065acd-0-1, but the properties were not set.
> The result was that the node is now there, but the primary type is missing (this is the error that Oak core was reporting).
> {code}
