I have one plugin for my server doing this things:

1: If one cheater using cheat for flyhack like ladder one, he gets kicked instantly (working good)

what the """error""", """bug"""?

If one player place a Mining Quarry and climb the ladder up the player is instantly kicked...

If anyone can help me fix it, I'll be eternally grateful Thanks you

Code:

using System;
using System.Collections.Generic;
using System.Linq;

namespace Oxide.Plugins
{
    [Info("LadderFlyKick", "Sergioklv", "1.0.0")]
    class LadderFlyKick : RustPlugin
    {				
		
		private static List<ulong> LastDetect = new List<ulong>();
		
		private void OnServerInitialized() => RunCheckLadder();				
		
		private void RunCheckLadder()
		{							
			var affectPlayers = BasePlayer.activePlayerList.Where(x=> !x.IsSleeping() && !x.IsDead() && !x.HasPlayerFlag(BasePlayer.PlayerFlags.ReceivingSnapshot) && x.modelState.onLadder && x.FindTrigger<TriggerLadder>() == null).ToList();
			foreach(var player in affectPlayers)
			{
				if (LastDetect.Contains(player.userID))		
				{					
					Puts($"Jugador {player.displayName} ({player.userID}) Fue kickeado por usar: FlyHack");
					player.Kick("Fly hack dected?");				
				}
				else					
					LastDetect.Add(player.userID);
			}		
			LastDetect.RemoveAll(x=> !affectPlayers.Exists(y=> y.userID == x));						
			timer.Once(4f, RunCheckLadder);
		}				
		
	}	
}
