How come Ihave been kicked out of the tournament even with the right requirement

Made it to week 20 of the Leap Frog Tournament, me and DeathofRats1963 both got the right amount to stay in but the system has kicked us out. Can this be sorted or not?

Possibly a timezone or sync issue. I see you don't have a flag displayed on your profile, so check in your settings that the site has your correct timezone.
Then check the timestamps of when you earned the first trophy in the period and check it didn't go into the previous period, and also check you did not earn the last one so late that it did not sync and scan in time. Did you do a manual scan on TT with plenty of time before the period ended?

Dunno about the OP but DeathofRats said he didn't have any syncs left so he could not scan in time.
