scheduleSyncDelayedTask Doesnt work!

Hello! I am making a plugin (as you understand). And i am using the scheduleSyncDelayedTask to give next effects after a while, but it doesnt work!
scheduleSyncDelayedTask works only between 0 and 40L! i've tried so much, but that didn't help.

player.addPotionEffect(new PotionEffect(PotionEffectType.BLINDNESS, 60, 0, false, false));
player.addPotionEffect(new PotionEffect(PotionEffectType.SLOW, 60, 3, false, false));


plugin.getServer().getScheduler().scheduleSyncDelayedTask(plugin, new Runnable() {
@Overridepublic void run() {
player.addPotionEffect(new PotionEffect(PotionEffectType.CONFUSION, 140, 0, false, false));
player.addPotionEffect(new PotionEffect(PotionEffectType.REGENERATION, 140, 3, false, false));
player.addPotionEffect(new PotionEffect(PotionEffectType.SLOW, 140, 1, false, false));
}
},60L);

 

The problem you're having with your plugin is that you're trying to set the delay to 60 ticks, which may be too short a time interval for some effects. Try increasing this value to 120 or even 140 ticks to ensure all effects are applied correctly. You will also need to make sure that your plugin is configured correctly and takes into account all aspects of asynchronous work in the Minecraft API.
