Thats very weird.
Are you using the latest version of FlowCanvas?
Does this happen in Windows Standalone as well, or any other platform you are able to build to?
Finally, can you send me the project to see what can potentially be going on?
Oh, I didn’t…
But now I did and indeed saw the problem.
The issue is the Debug Event in the “Mgr Score” flowscript. Please disconnect it before building and the null reference will no more appear.
I will of course fix this properly in the next version.
