Here's a fun service studio bug... Open the development environment, open a lot of modules (to the point where the next module you open will be in a new Service Studio instance).

Now, open your QA environment in another Service Studio instance.

Next, open another module in your development environment, and see what happens... It opens your module from development, and places it in your QA Service Studio instance! If you were to publish, it would be in the wrong environment.
Humm, you just tested and it happens.

Did you submit feedback on it in Service Studio?
