There are a few things that have changed through the plugin, such as paths being added, others removed perhaps and others modified. I suggest you allowed voidchest to load all files again and you replaced what ever appropriate. If you happen to ignore this move, you'll encounter issues such as errors, odd behaviour ingame or unexpected results.

• ADDED ➜ The option to play a sound when you click on any item on the voidchest menu inventory.
  
• ADDED ➜ The ability to change the default sell notification option for players.
  
• REMOVED ➜ Removed some code from the plugin that attempted to fix an issue with servers having duplicate data in the world's folder for the same player. This occurs when you usually change from online mode to offline and or vise versa. This issue resulted in plugins like vault (regarding economy) to break and not function properly.
  
• ADDED & CHANGED ➜ Added 2 new placeholders and changed an existing one. This is regarding the booster placeholder.
  • %booster% ➜ This previously showed the voidchest's booster. It now shows the player's booster and the voidchest's combined.
    
  • %booster_voidchest% ➜ This shows the specific voidchest's booster only.
    
  • %booster_player% ➜ This shows the player's booster only.
• ADDED ➜ A new event named VoidSellChunkItemEvent. This will be fired each time an item inside the voidchest chunk is about to be sold.
• ADDED ➜ A new feature named chunk collector. This will allow your voidchest to sell any sellable item inside the chunk it is located in. This feature will obviously be toggleable and mostly configurable.
• ADDED ➜ VoidChest chunk limitation. You can now limit players from placing more than 1 voidchest per chunk.
• CHANGED ➜ Material handling updated. Certain newly added materials were not working in voidchest due to using an "old" material parser.
  
• ADDED ➜ You can now allow certain voidchests to work while their owner is offline and others not. A default value will be selected from the options.yml `Sell.disable-when-owner-offline` path if the path `disable-when-owner-offline` doesn't exist in the specific voidchest file.
  
• ADDED ➜ You can now toggle an option to prevent players from placing normal chests near any voidchest. This will be located in the `options.yml` file and will have two different paths. By default, this option will be disabled, you may change it.
• FIXED ➜ Fixed a bug with the Hologram plugin, when voidchest uses it to handle holograms, having the charge feature disabled, it would not show the sell countdown and instead show `No Fuel`.
