Expected Behavior

Pressing the plus button labelled "Fill Recipe" would move all items in my inventory to the crafting table in the arrangement necessary to craft this recipe:

Actual Behavior

Pressing the plus button labelled "Fill Recipe" occasionally fills some or none of the recipe's items:

Steps to Reproduce

1. Create a new world
2. Gather the ingredients for a crafting recipe and place down a vanilla Crafting Table - the bug isn't consistent, and it seems that the more tools are involved the more likely the bug is to occur. Most have experienced this bug when crafting a Maintenance Hatch.
3. Ensure one of the tools is damageable. (i.e. not made of Neutronium) It is simplest if you use all Iron tools except for the mallet, which can be Silicone Rubber.
4. Empty your hotbar.
5. Craft the recipe once to damage all of the tools that can be damaged, and exit the crafting menu. This should put all of the tools involved in the craft on your hotbar.
6. Change the active hotbar slot to a remaining non-tool slot
7. Save & exit from the world, then rejoin it. (Unsure if this is necessary, but try it anyways)
8. Switch the active hotbar slot to the aforementioned tool using one of the number keys or scroll wheel.
9. Open a Crafting Table and try to craft the recipe again using EMI's "Fill Recipe" button.
10. If it does fill, scroll to another tool (they should all be in your hotbar) and try to fill the recipe again with the next tool in-hand.

Additional Information

When performing the recipe according to the instructions (Iron tools, silicone rubber hammer all in hotbar, last slot empty) the tools that caused the bug to occur for me when their hotbar slot was selected were the Iron Screwdriver, Iron File, and Silicone Rubber Mallet.

Cross-posted on the Gregtech Modern issue tracker

For me and my friend it's usually the hammer that causes issues.

If there's a hammer in the recipe, often times all items after (and including) the hammer don't get put in. By "after" I mean going right then down.

This is also what happened in the screenshot that was already posted here.

Bump

There is no need to bump an issue tracker

It's not visible on the issue I linked, but the Gregtech modern devs said the same thing when I bumped this issue's counterpart. 💀
I suppose I'm too used to support forums where an issue I make must be kept within the top few most-recently-updated posts or else it'll be buried and forgotten like how fish bones fossilize at the bottom of the seafloor.
Glad to hear that this won't be ignored, too.
