Subject: [PATCH] Optimize UserCache / Thread Safe
|
|
|
|
Because Techable keeps complaining about how this isn't thread safe,
|
|
easier to do this than replace the entire thing.
|
|
|
|
Additionally, move Saving of the User cache to be done async, incase
|
|
the user never changed the default setting for Spigot's save on stop only.
