I have been using Game Creator without any problems and love it. I bought all the modules with it and am just now trying to create a new Behavior. However, that option is NOT available to me. I have installed it, and I installed its demos. I ran the demos and they seem to work. When right-click in the Hierarchy tab and try to add a new behavior, the option just isn't there. I'm using unity 2019.2.2f for this project and did not want to upgrade if at all possible, considering my version should be supported.
