[20:09:10 WARN]: [Essentials] Task #159091 for Essentials v2.17.2.99 generated an exception
java.lang.RuntimeException: The operation to load user data for 'd6988abb-0d7e-4a65-93ca-5a61855a16a0' was cancelled by LuckPerms. This is NOT a bug.
The lookup request was made on the main server thread. It is not safe to execute a request to
load data for offline players from the database in this context.
If you are a plugin author, please consider making your request asynchronously.
Alternatively, server admins can disable this catch by setting 'vault-unsafe-lookups' to true
in the LP config, but should consider the consequences (lag) before doing so.
