I'm unsure if this is on purpose or not, but if you have a Retrieval Task set to Consume=false, you have to have every item in the task to complete it.

If Consume=true, you can detect/submit the items one at a time.

Is it possible to change it so that Consume=false works the same way? (So, if you have a task that asks for 3 sticks, 5 iron ingots, 1 iron pickaxe, and 1 iron sword, you don't need double the resources to complete the task).

I will likely change this but it will have to be after I finish the rewritten build of BetterQuesting

What I do is two separate tasks. That way you don't have to have all the items together. works fine.

Yea retrieval Quest have to be consume=false as default not the other way around.
If this can be changed would be great.
