This is a known issue with the latest bungee builds. I am just awaiting some free time to investigate the error. Are you having any negative effects or things not working, or is it just the stack trace?

[Blskk]

这是最新蹦极版本的已知问题。我只是在等待一些空闲时间来调查错误。您是否有任何负面影响或无法正常工作，或者只是堆栈跟踪？

No other issues

[BGHDDevelopment]

Just tested and I am unable to reproduce. Can you give any other details on when this exactly happens?

[BGHDDevelopment]

PB2.3.5.zip
If you want you can try this version, however I only added a try and catch to see if the error can be hidden. Without reproducing it I can't find a cause.

Yes, it successfully solved my problem

Thank you.
