Thank you very much for taking the time to provide us all the details.
Sorry to hear that you are fully stuck and can't complete the demo.
We'll do our best to fix it as soon as possible!
We are able to recreate the issue, so we are one step closer to fixing it! Thank you again!
It appears the issue happens when drag-and-dropping the spanner over the sign/bolts but not when clicking to select the item and then clicking on the bolts.
