Now notice that the token is moved to place pe in the mainprocess and that the token isn’t moved to place pe in the subprocess. Which is inconsistent. The token should (in my view) be at the same place in the same time.
If you complete t2 in the mainprocess, then t3 will be activeted too early. I have noticed that WoPeD doesn’t allow you to complete t3 until the subprocess sub1 is closed. But that isn’t the way it should work, because due the activation of t3 is will generate tasks for users or automatic tasks before the subprocess is completed.
