mod and plugin conflict

Greetings. I wrote a plug-in for the "Capture points" mode. I put "Mohist" on the core. Put the mod "techguns". As soon as I start the game with the command, the player is teleported to the right coordinates, but the camera flies into the void. There is a feeling that the player is in the abyss. This happens to all players on the server. If you remove the mod, everything works fine.
game start code:

Code:

 starting = true;
        board = Bukkit.getScoreboardManager().getMainScoreboard();
        try {
            playerKillAmount = board.registerNewObjective("scores", "dummy");
        }
        catch (IllegalArgumentException e)
        {
            playerKillAmount = board.getObjective("scores");
            playerKillAmount.unregister();
            playerKillAmount = board.registerNewObjective("scores", "dummy");
        }
        playerKillAmount.setDisplayName("Очки:");
        bluesc = playerKillAmount.getScore(ChatColor.BLUE + "Синие:");
        bluesc.setScore(0);
        redsc = playerKillAmount.getScore(ChatColor.RED + "Красные:");
        redsc.setScore(0);
        playerKillAmount.setDisplaySlot(DisplaySlot.SIDEBAR);
        for (Player player : Bukkit.getOnlinePlayers())
        {
            if(Bukkit.getScoreboardManager().getMainScoreboard().getTeam("red").hasPlayer(player))
            {
                player.teleport(new Location(Bukkit.getWorld("world"), redSpawn.getX(), redSpawn.getY(), redSpawn.getZ()));
            }
            if(Bukkit.getScoreboardManager().getMainScoreboard().getTeam("blue").hasPlayer(player))
            {
                player.teleport(new Location(Bukkit.getWorld("world"), blueSpawn.getX(), blueSpawn.getY(), blueSpawn.getZ()));
            }

           


        }
        counter.start();
    }

counter:

Code:

public class Counter extends Thread {
        public void run() {
            for (Player p : Bukkit.getOnlinePlayers())
            {
                block(p);
            }
            Bukkit.broadcastMessage(ChatColor.RED + "5");
            try {
                sleep(1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            Bukkit.broadcastMessage(ChatColor.RED + "4");
            try {
                sleep(1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            Bukkit.broadcastMessage(ChatColor.RED + "3");
            try {
                sleep(1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            Bukkit.broadcastMessage(ChatColor.RED + "2");
            try {
                sleep(1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            Bukkit.broadcastMessage(ChatColor.RED + "1");
            try {
                sleep(1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            Bukkit.broadcastMessage(ChatColor.RED + "GO!");
            for (Player p : Bukkit.getOnlinePlayers())
            {
                unblock(p);
            }
            starting = false;
            isGameStarted = true;
        }
    }

Has anyone met with this?
