The rolling machine cant not make the item.Sometimes it works fine, but sometimes it will not work.And in the REI.Sometimes i can left click to see the recipe of the rolling machine's item (eg. heating coil),but sometimes it can't. By the way, i am running it on a server,lots of player have the same problem.

fabric-api-0.3.2+build.212-1.15
(have the same problem in older version)

Pleax fix it,Thanks.

This isnt working as you have the lock enabled, this lock is there to keep atleast 1 of each input in the machine. Adding more items or disabling the lock will fix it.

Sorry.But i still think there are some issues.
I try again.And it only work one time .Even i unlock or adding lots of items.
If I do something wrong, I am sorry to bother you.

No worries, ill reopen the issue and take a look when I get a chance.
