No, because I checked directly before collecting, hence my confusion and anger!
I took a snapshot of what I have now 14 hammers/ 10 chisels.
I will be collecting in half an hour, we'll see how the numbers will flip around!
Edited to add : Collected now, and back to 11 chisels/ 15 hammers.
Hopefully that was one glitch, which is happening alot these days, also resetting!
