error Error: Cannot read property 'Start' of null

Hi all, 

I am trying to add a change to the calendar using variables from a task but keep coming up against this error: 

The BPM looks like this:

And the task setup like this: 

Add to calendar node looks like this:

I am supposed to be presenting this this afternoon so any help to resolve will be greatly appreciated (as always)

Edit: I added the 'Get request info' after the first failure in the wild hope it would work. There was no change (to be fair I didn't expect there to be)

Did you copy/past some nodes form one place to another? If yes then you need to recreate references...

@Victor, yep that was it. Missed one  

I was going mad trying to find it lol. 

Now the only issue I have is when the workflow jumps a phase, the stage checkpoints don't line up with the phases:

So in the screen shots 'Assessment' has been skipped but the stage checkpoints remain under 'Implementation'

'Implementation's checkpoints are under 'Review' and the ones for 'Review' are missing altogether...

I have refreshed the page (and the cache) with no fix

@Dan Munns possibly a defect... raise it with support so they can have a look
