Again this week, I have yet to find a scrimmage late in the week, and my upcoming cup game is replaced where the scrimmage finder would show me possible scrimmages.
There were several instance of breakage of the fix, but this should be fixed at this point.
I imagine what you're talking about is a slightly different issue where the National Tournament game appears in the SC finder box immediately after the off-season updates, cutting the SC arrangement period a couple of days short.
