I routinely play Rimworld, with a large number of mods.
Since the move to A13, and the updating that has happened to mods, there seems to be an incompatibility issue between VeinMiner and HaulPriority Lite, whereby in the Orders tab, the last three controls are from which of the aforementioned mods is loaded last by the game.
Is there a way to expand the "empty" controls, so I can have the controls for both VeinMiner and HaulPriority?
Yep, but the solution that I found ain't for the luddites! It requires some minor changes to one of the xml files in one of the two conflicting mods.

Thanks very much for your help. I was able to get the two mods to play nice together.
