Since the Discovery Release i cannot add a script into certain kinds of objects.
In such same objects that already contain a script i cannot replace the script by a newer version. I can still see the parameters of the script inside, but there is no more dropdown to select a script.
In the Scene Object list, these objects lack the blue triangle at the left.
As a consequence (for example) i can no longer add (or change) a script to a Wooden Door that would make the door open/close.
As a Coder i completely rely on the ability of scripting all sorts of objects when i create an experience.
This BUG is absolute FATAL for my work!
