I got the same issue, after i updated aslain modpacks and had to restore WoT because the ssd died i no longer see the numbers
I have reinstalled it about 5 times now and did a total clean mod setup but the stats and winrate does not show up any more
Not sure what i can do to get it back working again.
Or does it need weeks to become active again or so ?!??
That means Pop is not alone
