[Fixed] Fixed a SERIOUS BUG: In a special environment, after performing specified steps on a merchandise, data replication issues can occur due to player exploitation. Please update to the latest version as soon as possible to avoid this problem from happening.
[Fixed] Fixed some possible asynchronous operation issues (which may result in locks), optimized the underlying code, and addressed the issue of high workload for some tasks.
NOTE: To ensure thread safety, starting from this version, NewMailEvent in the plugin's API will no longer support changing parameters and canceling event operations through listeners.
