As it says. I have a complex priority system I try to keep up - my main factory has high priority, research the lowest. This is nice, as rare things go to the factory when requested.

Except they do not. Priority seems to be ignores once an item is queued. My low priority stations end up in the queue - and then move up in it while higheler priority stations are below them.

Deliveries should always go to the highest priority station requesting them.

Hi. Priority currently only affects supply station selection if there are multiple. The request queue is indeed not sorted by station priority. But it seems that it is not difficult to do. I'll think about it. Thank you.

You do not need to sort - what you can do is simply when processing a queue look a the first item, priority, walk along the queue and replace the item to deliver to when you find one with higher priority. At the end (and queues are not long) you end up with the highest priority target. May be WAY more efficient than a reorder.

The problem is that the priorit is critical - because queues happen when an item is rare, so THEN you want priority to matter.
