In some cases, a player's inventory may be corrupted or they may be stuck in a corrupted chunk. This could cause the player to be unable to log into the server and, in some cases, cause their game or the entire server to crash.
Although resetting the world will fix this issue, this would mean loss of any or all world changes which may not be ideal for your server. An alternative way to fix this is to manually delete that player's playerdata (.dat) file, which will reset their inventory, location in the world, and other Vanilla Minecraft-based player data. As most plugin data are stored in the respective plugin folders, these will not be affected.
# How to Find and Reset a User's PlayerData
You will be required to identify a players UUID then remove the DAT file from the server files.
- Identify the player's UUID. You can do this by searching for a players username in a website such as NameMC.com.
What is a UUID?
A UUID is a unique string of numbers and letters, seperated by various dashes. Each Minecraft player will have a unique UUID assigned to their account as a form of universal identification.
- Access your control panel and Shut Down your server.
- Navigate to server files, and navigate to
/world/playerdata. - Select the DAT file that contains the players UUID that you previous identified in step 1, and delete it.
- Start your server.
