someone spelled nails as nailss.
All pluralized items get an ‘s’ appended to the end of their name. It’s only correct half the time, but it’s what we have right now.
Also you get bonus Smeagol jokes for free.
“Lookitss all the nailss Preciouss!” 
simply remove the s at the end. also it bugs out when you craft and crashes if you exit to the menu and reload.
remove the s at the end
That’d be kind of messy in code, don’t you think?
