Hey @Thomas84 ! Thank you very much for reporting this. Could you please provide a quick translation of that Dynamo error window?

[Thomas84]

There is an Error and Dynamo has crashed. We are soooo sorry :) You have the chance to save your work before we kill your application.

and the error log: The object reference was not set to an object instance
