I found a workaround for the TPU stats problem that started on January 1, 2020. It involves changing the year of each round from 2020 to 2019. Yes, it's clunky, but it works.

None of the round, map, or player stats refer to dates, so this doesn't actually mess anything up. Well, nothing important anyway.

The only place on the stats page where year is now showing as 2019 when it should be 2020 is in the server stats section towards the bottom:

SERVER STATS
Server has logged rounds from 2019-01-01, 04:01:43 to 2019-01-05, 04:49:30

UPDATE 2020Jan07: I found a workaround for the year being wrong in that one spot on the stats page.
