love the mod!
just one thing, since the hauler can haul more than one chunk at a time, can u make the chunk forbiden when it fall off? otherwise it is really unefficient that a hauler run ten miles just to haul one chunk. or maybe like the old fashioned chunk which need to use the "haul" oder.
I do like the idea of having them spawn like standard chunks, requiring the haul order to be moved. I'll look into that.
EDIT: Just posted a quick bugfix update. Apparently I forgot to make it so that traders didn't carry unprocessed stone chunks.
From what I can tell, this fix does not break existing saves, so can be applied without worry. I recommend making a backup copy of your save just in case.
I've left the v0.9 version available in the attachments section of the OP just in case you do encounter problems using the new update.
