Looking at the results of the Federation matches to start the Federation League standings, I came across this match
#match?mid=5765409
Is this a bug?
I don't know how it's possible that this match has been concluded, but in any case it appears in the official list of federation matches

To avoid distorting the rankings, I don't know if an admin can cancel the match. Otherwise, as I'm ranking the top 8 federations manually, I won't take it into account

Similar scenario to this match #match?mid=5768796

The match was originally Croatia v Mexico, but the Croatian team no longer exists in the game and has recently been replaced by a random team. Maybe the same scenario with another nation whose team has disappeared, like Zimbabwe in your link.

There's no news at the moment about this bug, which means that the Croatian team will receive a call-up at 9.55pm this evening and potentially end up in a space-time rift.
