Almost every time you insert only 1 singular item into a chest connected to copper pipes, the game crashes.

I'm on 1.20.1, I assume this is fixed in future versions but I am running a modpack for myself on 1.20.1 so I am unable to move to 1.20.2. If you could please release a fix for 1.20.1 I would be very grateful.

Would you be able to share logs?

@Treetrain1 since you did the transfer api stuff do you have any clue why this would happen?

I have no clue without a form of context or logs

Sorry! I completely forgot to upload crash logs, here it is.

Seems to be an issue with Smooth Swapping

Thank you so much! That fixed it!
