If you dump stuff, it gets forbidden after being dropped. If you then unforbid it, the original dwarf will claim it again if it is on his Pri/Assignments list. To make sure the pick is available again to miners, you need to delete it from the first dwarf's Pri/Assignments list using my other tip:
To delete those pesky items from the Pri/Assignments page you have to go back to the equip/view page, assign the dwarf the specific item you want rid of, then simply delete it - this tells the game to delete the item from Pri/Assignments page, and it should get dropped. If there are a bunch of indistinguishable items, you just have to assign and delete them one by one until the item disappears from Pri/Assignments.
Yes. Thank u for that tip - it worked for me. Partly... the first time i set it, my mil. commander equipped himself as i told him, not taking extra picks or armors, but my second soldier just continued staying and doing nothing. At the second time, it crashed -_- : militia commander, despite all my indications, took extra equipment, and the second soldier continued doing nothing. Could u tell me what did i wrong?
My actions:
1) Using your method, i cleaned all their Pri/Assignments. There is just list of their civilian clothes. And yes, before that, i disbanded them all, and they dropped everything they had. And then create a band again.
2) I began adding specific weapons and armors (cause i got only 2 soldiers and 3 set of armor)
3) I checked the Pri/Assignments list again - everything is alright, then i pressed ESC.
Despite that they had items in their Pri/Assignments list, they just continued "combat drilling" thing. Then i returned to Military, and tried to assign uniform (that consisted of spear, breastplate and shield - there is no specific armor/weapon option in uniforms - while i have 3 iron spear, 3 iron breastplate and 3 iron shield).
After assiging uniform - militia commander ran to get his equipment (and did it entirely correctly), while the second is idling - as i have described higher. Then i closed DF through manager and tried to do everything higher again, and my commander got two set of assigning armor, while second soldier is still.. erh... combat drilling. Naked
Please, tell me how to fix it. It's the second day already, that i cant play DF because of military stuff -_-
