tie game message when someone clearly won.

[RicardoRix]

There was a clear winner for this table:
https://boardgamearena.com/table?table=95325698

Yet it ended with a 'tie game' message:
https://gyazo.com/008389521e4a7d4a53f3ec9d248fa88c

I am using the gameinfo
'losers_not_ranked' => true,

Anyone know the reason?
