This is the healer personal inventory :

and here is one builder's rack :

and dmen passed there and picked up things several times? And the healer already dumped?

His chest is empty and he never dumps his inventory, so the dmen have nothing to pick up. They only deliver what is needed by the healer. I checked the researchers, for example, who don't dump either, and the cook's rack which has several stacks of leather.

the healer will dump, but rarely

when you click on the cook, to ask the dman to come by, will he take those things?

I asked for a pick up from the dman, had the confirmation in the chat, dman came but picked up nothing.
