Context: I was trying to unlock the required research so the mechanical user could autocraft using the Iridescent Altar, so I gave it a Knowledge Sharing Paper and ended up crashing the server.

Flagging as uncertain because may or may not be fixed as intentional to prevent non-real player usage...

But at the very least, should at least stop it from crashing the game. Because this could be done, on a server to crash it until the forge option to remove erroring tile entities is enabled. (like say... with a integrated dynamics player simulator that's in a chunkloaded area.)

That would be on exu's side, it's the source of the ticking entity.

Knowledge will not be given to fakeplayers anymore.
