   Hello @mattyb149,
   
   I've created a GenerateFlowFile processor which is running.  Created a 
version where only position changed.
   Added debug point at FlowUpdateResource updateFlow method and a debug point 
to StandardVersionedFlowSynchronizer updateProcessor method.
   
   At version change, without patch:
   FlowUpdateResource updateFlow runningComponents set contains 
GenerateFlowFile processor.
   StandardVersionedFlowSynchronizer updateProcessor goes to the 
updateProcessor if branch
   nifi-app.log shows FlowUpdateResource Stopping 1 Processors and 
FlowUpdateResource Restarting 1 Processors
   
   With patch:
   FlowUpdateResource updateFlow runningComponents set empty.
   StandardVersionedFlowSynchronizer updateProcessor goes to the setPosition if 
branch
   nifi-app.log shows FlowUpdateResource Stopping 0 Processors and 
FlowUpdateResource Restarting 0 Processors
   If my memory serves well only Updating Flow can be seen on UI.
