When a subscription server is down or not reachable, i can create new folders, content nodes, and node data, but I cannot modify them after that. That means, I can't give them a name (they stay as "untitled") and I can't remove them anymore. Once I set the subscription entry to "active:false", everything works again.

Also, there is no error message generated which hints at the cause of this problem.

For the user, the best solution would be if creating and modifying new entries is possible even when the subscription server is not reachable. I understand however that it's not possible to determine for sure if an entry was activated before. So, when a user tries to add or modify content when the subscription server(s) is/are not reachable, that action should be rejected with an appropriate error message.

I believe this is somehow related to MAGNOLIA-554, but different.
