I would rather not discuss potential ways to circumvent any aspect of the trial time limitation. As I have stated previously it could have been something unintentional or perhaps even something that you had no idea even happened, that is why I have offered to take a look at it for you. As this has never happened before I cannot say try X or do Y because it shouldn't have happened like that and I have no experience with the trial ending sooner than expected so would have to take a look at it myself.
