Players can craft items while offline and you do earn experience points for crafting offline. As of Patch 2.4, the offline crafting time limit has been removed. Instead of a time limit, players have different crafting queue sizes based on their subscription type. Scavenger accounts have a limit of 1 item. If you ever buy anything from the store, the limit increases to 3 items. Survivalist accounts have the current limit of 20 items. Wastelander and Commander accounts have a limit of 30 items. Most low level Recipes in Armorcraft, Weaponry, and Ballistics have had their crafting times reduced.
