Vizzy not set to an instance of an object

@pedro16797 ok. I think I can fix it. Thanks for the help.

btw, if you use wait 0 it's the same as using wait time delta frame

You are making widgets in one thread and removing them immediately in another. This makes the destroy run before all the widgets are generated and can then make widgets with colliding names depending on when each block is run.

I would recommend not deleting and making all widgets per frame, and you should be careful when making widgets with names that already are in use.
