How do I catch this when it only happens for some players?

Capture it automatically from the player's device with the full stack trace, the device and OS, the build, and a breadcrumb trail of what they did. That turns a vague complaint into a specific, reproducible issue you can fix without owning the hardware it happens on.

How to Fix a Crafting Recipe Matching When Extra Ingredients Are Present

Q: What causes a crafting recipe matching when extra ingredients are in the grid?

Recipe matching only checks that all required ingredients are present, not that nothing else is, so a grid containing the recipe plus extra items still matches.

Quick answer: Require the grid's ingredient set to exactly equal the recipe's required set, rejecting any match where extra or unexpected items remain.

If a recipe fires even with junk items added to the grid, matching is checking for a subset, not an exact set. Require an exact match. Here is the fix.

How to fix it

1. Compare full ingredient sets

Match a recipe only when the multiset of grid ingredients exactly equals the recipe's required multiset, not merely when the required items are a subset of the grid.

2. Reject leftover items

After confirming all required ingredients are present, verify there are no extra non-empty slots, so a grid with extras does not satisfy a recipe meant to be exact.

3. Respect shape for shaped recipes

For grid-shaped recipes, match the exact relative positions of ingredients, so the same items arranged differently do not incorrectly satisfy the recipe.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.

Most of the time the fix is small. Seeing the failure clearly is the part that actually costs you.
