They may be doing it for the releases of the sim, they aren’t doing it for store releases. They test on their test servers, the package it with encryption for the i game store. The thing is, these two addons are probably calling some API function that not everyone is, or calling it differently. You would have had to have a client be outside the Microsoft network, and calling the API function exactly as these packages do, in order to find that bug. It’s a missed test case. It happens. Comprehensive testing is only as good as the test cases you have. But you can’t paint is as a failure of the entire testing methodology. It was a test scenario no one thought of.
It is disappointing we have to wait, but I a, not going to fault a single party in this at all. This was an obscure bug that was pretty easy to miss.
