Additional context
Using the source code provided with this project, I could create a new GameProfile object in the constructFakePlayer() method of TaterzenNPC.java before trying to create a new ServerPlayer object. This was an immediate resolution to the error I was getting; however, depending on the overall code structure, which I have not studied intensely, this could require more updates. Thank you for taking the time to look into this report.
