It's definitely not a problem with temporary internet files. After the fix, it worked for a while, and then this week (I still do not have my final flag, Barbados, where there are only four active teams) it refused to work until the scrimmage options were closed down on Wednesday. Now it works again, and I have issued challenges to the four Barbados teams. If they do not accept, but arrange other scrimmages I fear it will happen again.
