Hey, @miggidymack. Welcome to HWS.
This can happen due to a constructor bug, where it’ll craft an item, consume the resources, but not actually output anything.
It’s unfortunately a quite common bug, and can’t be avoided entirely. Frequent game restarts can help though.
We don’t have any logs over it, so we normally can’t help, unless you can provide us with a video of the loss happening from within the constructor.
In general, recording your Empyrion gameplay is highly recommended. The most expensive bugs are usually also the ones we don’t have logs over.
But as a one-time exception, I’ll take your word for it. I put it in your inventory now.
