The only tool I had with me was the pick, so I don't know about the rest of them. If it happens again I will go home and check the rest of the tools also. I had ores, bars, stones and a flower in my inventory.
Also it was the first thing I did that day, go to the mines. I didn't even have to use the watering can before because it was raining.
I exit the game and when I loaded again everything worked well so... I don't know.
