I'm not sure if it's a bug or ment to be this way but for some reason using the Tanning Tubs, Kilns, and Looms you do not gain any XP towards your Professions which is 50% of the crafting you have to do. I think we should be obtaining some sort of XP for the task being done.
#XP for the Passive Crafting

Yeah was gonna suggest the same. A chunk of EXP upon completion would be huge.
white lance
the one problem is they don't limit who can do this so players can process for the settlements as a whole. with this they'd have to limit it to player level too

This would also likely halve the xp we gain from active crafts so keep that in mind. And balancing between passive and active crafts if they both give xp sounds like a huge hassle. It might also cross the line of "buying xp" since you can buy mats to do infinite passive crafts at the same time. So I'm gonna go with negatory on my opinion
