Hey, i have had people complain about lag on the server when interacting with boxes. I orignaly thought it was server lag, although when i did some testing and removed his VIP status, it was instantly fixed. Then i gave it back to him and went through the plugins and found out that QuickSort was the one causing the lag when interacting with the box. Hope you can get this fixed as i currently have upwards of 100 people with VIP complaining (I have temporarily removed the plugin).

Should be fixed in latest version
