I got the same Issue in the new Release- Version: minecolonies-0.13.81-RELEASE-universal.jar

Can you try the latest alpha?

I'm not sure if this is related but I get deliveryman AI error in version 171-Alpha

With 171 Beta, courier just ignore the Stash after the first use. They will come pick up the stuff I put inside if I break the Stash and place it back again.

In the latest this shouldn't happen anymore then

Small addon to this bug : the stuff in the Warehouse Hut (not in the racks) doesn't count as stock. The villager won't see/use it.
It was already the case in the previous version I was using, and still now.

And sometimes, when you press Sort, it goes into the hut block.

This should be fixed int he newst. But needs a rs-reset
