Some users reported that after reopening a project, all of its diagrams appeared in a disconnected state, even though the diagrams themselves were fine. Opening each diagram by hand and reconnecting it worked without any problem.

The cause was that a diagram's connected state could be lost when saving: if the automatic diagram synchronisation that runs during save was cancelled or interrupted, the project remembered the diagrams as disconnected. On the next open, every diagram therefore came back disconnected, which did not reflect what the user had actually set up.

Newly created diagrams could also be stored as disconnected, and the 'Connect all' / 'Disconnect all' action on a multi-selection only affected the currently open diagram instead of every selected one.
