The same thing happened to me, one player disappeared.
And I have already fought him 3 times.
I checked the point history of the script and the points already earned from him were not lost.
Also the same thing happened on the test server, 2 players disappeared.
I am wondering why multiple players disappeared at the same time.
These codes work on the browser console.
You need the community script (hh-plus-plus).
Show disappeared players:
(function(w){Object.entries(JSON.parse(localStorage.HHPlusPlusLeagueResults)).forEach(([id,data])=>{if(!w.leagues_list.some(e=>e.id_player==id))console.log({id,...data})});})(document.querySelector('iframe')?.contentWindow??window);
Show the point history of the script:
console.log(Object.entries(JSON.parse(localStorage.HHPlusPlusLeaguePointHistory)).map(([id,{points}])=>[id,...points].join('\t')).join('\n'));
P.S. The name of the disappeared player is Alucard. So I am not in the same bracket with @Ravi-Sama.
