This is how to reproduce the bug (ovbiously it work whit other numbers of items but this is an example)
1-pick 100 iron plate and 150 copper plate
2- craft 100 green circuits
3- cancel all the cables for the circuits
4-recraft all circuits you can
my remaining materials where: 100 green circuits and 138 copper plate (i should had 0 copper plates)
i recreated this 4 times whit a 100% succes chance
i didnt try any other objects, only whit green circuits
