[MC-122703] You can craft a stack of non-stackable items using data packs

The bug

If I add a recipe via data packs, that shoud craft a non-stackable item (ex. diamond sword) and I add a count, that is bigger than 1 (ex. 64) I get the amount of items in one stack. This works for any integer.

Attached is a sample data pack for testing (

Is this still an issue in the latest snapshot 18w20c?

Yes, it is

It seems like you add the diamond sword to 64, but if you turn it to higher like 128? It will crash or something? Idk

Just tested it, this works for any integer. No crash occurs.

This issue affects 24w09a but not 24w10a (it now produces an error message about the stack size being larger than the maximum). This issue was fixed in 24w10a.

Fixing this has actually caused so much trouble for me when it comes to data packs… Wish this would have remained the way it was… Would have been so much better…
