PrisonEssentials/ScoreHud

So I used the API from a plugin and made an addon for ScoreHud, and well I'll just show you what happens when someone who is rank Z joins the server and the Scoreboard updates:

Code:

[205]         foreach($this->prestiges as $index => $prestige){
[206]             if($prestige["tag"] === $name) return $prestige["money"];
[207]         }
[208]         return 0;
[209]     }
[210]
[211]     public function calculateMoney(Player $player) : int{
[212]         if($this->getNextRank($player) === ""){
[213]             if(isset($this->players[$player->getLowerCaseName()]["prestige"])){
[214]                 return $this->getNextPrestige($player) !== "" ? $this->prestiges[$this->getNextPrestige($player)]["money"] : 0;
[215]             }
[216]         }
[217]         return $this->ranks[$this->getNextRank($player)];
[218]     }
[219]
[220]     public function removeAllPermissions(string $player) : void{
[221]         foreach($this->ranks as $rank => $price){
[222]             if($rank !== $this->getDefaultRank()) $this->getPurePerms()->getUserDataMgr()->unsetPermission($this->getPurePerms()->getPlayer($player), strtolower(str_replace("{rank}", $rank, $this->getConfig()->get("permission"))));
[223]         }
[224]     }

Does anyone know how this would be fixable?

 

There's like 10 thousand functions used in those two functions.
Mind sending the whole code and the error?
