It's only a half-bug really. It's because people are saving strategies after race preparation gets locked. The issue is that we allow people to do that at all.
I think I need to add a countdown to when it's going to lock and then prevent anything from being submitted after that.
i guess you can use this bug for exploiting, so that you can run your qualifying with SS and then change the tyre to S, M or H. So i would really call it a full bug.
