I built a hunting lodge which put 12 pieces of leather into my storage barn. I assigned a tailor to my Tailor shop but a whole season later it says the tailor can’t work because he has no leather. The leather from  my storage barn no longer has the 12 pieces of leather.

Does something else other than the Tailor use leather? I’m early in the game so only have smithy, gatherer, farmers, forester, fishing port and hunting lodge down.

I have no trade port so it hasn’t been traded away.
