The New Sudoku Players' Forum

[beachcomber6]

This site has a number of competitions, including a weekly 'Extreme' level which I find quite challenging.
I also tend to post my solutions days/weeks in advance and am equal top (with about 50 others) of the Extreme competition.
Every new year, the system software falls apart in one way or another regarding the Extreme.
This year it has wiped out all of my history up to the end of 2025.
Anyone else having this problem?
