Describe the bug
Server crashed after player inserted Magnet Card into Wireless Terminal.
(Inserting into the Wireless Crafting Terminal will not cause any problems)

When the server is restarted, the player is unable to join the server with the message "a fatal error has occurred, this connection is terminated".
After removing the Wireless Terminal from the player's inventory by NBTeditor, the player can join the server again.

Cannot be reproduced in single player mode.

do you have the crash log ?

In my case, the server did not crash, but did generate a traceback and prevent the player from rejoining.
