It's happened again. That thing that plagues us all when building. You put down a piece and it disappears! Or it is accidentally bumped off the table and you can't find it, or you push something together only for it to explode, the pieces go flying and also disappear.
This just happened to me and like Samuel L Jackson's character at the end of John Wick 3: "I am really pissed off"
So, what strategies do people have to mitigate these issues?
I was building in an area unusually free from any Lego pieces (it's all been packed away and I was just swapping some pieces from one MOC to another). The floor was also relatively clear but the piece I've lost is gone forever!
I have heard of non-Lego modellers tucking a serviette, piece of cloth, dishtowel etc. between themselves (when seated at a table) and the table so that any pieces that roll or fall off simply go into the cloth and can be easily retrieved instead of bouncing/rolling away on the floor.
This isn't always practical however, especially if it's just a quick MOC or seeing if something works.
