Heyhey
I finally get around to trying all the newstuff in VL! Fun.
I got around a bug: when I click on the little gray arrow to the right of an operation, like that:
(I’ve made a second input called Result in this case, but this has nothing to do with the crash. Also happens when there’s only one input)
When I try to interact with the inputs, I get an error, and vvvv crashes. Here’s the error message:
************** Exception Text **************
System.NullReferenceException: Object reference not set to an instance of an object.

vvvv crashes when I try to patch after this error - windows says ‘The program has stopped working’
I haven’t found which interaction lets it crash - I was able to select it once, but after deselecting and selecting again it crashed. Also when trying to move or rename them it crashes.
Hope that helps, tell me if I should try anything else.
