When using the shift - upgrade planer to cancel upgrade orders, underground belts can become disconnected.
Upgrading one side of a underground belt places upgrade orders on both sides of the underground belt. Canceling the upgrade on one side of the underground belt does not cancel the upgrade of the other side, but instead disconnects the underground belt.

Not a bug. 95772 70011

If you don't want to fix it i understand, it is not a important bug.
No need to make up some excuse that this is wanted behavior.

This was the reasoning, why the behaviour is intended.

That might change in the future but for now that's what was decided when we made the feature.

I can follow this argumentation somehow. On the other hand, if you do something and cancel it, the expectation is usually, that you don't have a different state afterwards. f.e. if you do a booking, then make a cancellation, it has to be like nothing happened.
