The problem stems from the DB's packet reading system. There are issues that cause packets to not be read completely during heavy operations, and some packets to be lost or corrupted. If the lost or corrupted packet is an item recorded after a trade, then this problem occurs. Reducing the number of packets sent to the DB does not provide a complete solution; the problem persists, albeit to a lesser extent. The definitive solution to the problem is to rewrite the DB's packet reading system from scratch. The system must be able to read packets completely and accurately. This is a somewhat detailed and delicate process with a high risk of error. Only experienced individuals should perform it.

The biggest fundamental flaw is that players and monsters use the same class and packet communication. This error causes unnecessary memory usage and unnecessarily long processing times. Action on this issue is only a minor improvement. More improvements should be made for large projects. All source code should be modular and independent of each other, with small packet communication and short processing times.
