I wasn't aware that harvesting nodes were PCs in this game, do you converse with them also? Wait.... do you hear them ronin? Do you hear the voices too?!? The harvesting nodes... they tell me things, many many things. They speak to me the secrets of Atys and many other things, like what color is in fashion for a given season. The harvesting nodes are vast in their knowledge of things indeed, if given the chance I suggest that all my fellow homins listen to these wise harvesting nodes.
Incoherent raving aside, as far as I know ctrl+space only targets PCs, PC standing for Player Character being you, me, the other guy, or the chick from the other day that was in that one place killing that one mob with that one weapon. Correct me if I'm wrong on the function of ctrl+space, also I have yet to have this targeting issue while using the space/ctrl+space methods. Using the mouse to target anything in a group is.... not an effective means for targeting due to the rather inaccurate targetting boxes.
Perhaps a GM/mod could clear this little bit up for me? Being right or wrong I'd like to know the exact nature of this O' so mysterious targetting method. For the knowledge of the harvesting nodes is rivaled only by the GMs and devs.
P.S. Baldy, how big of a minefield do you want? I was thinking of making a vast harvesting node field with thousands of sources with a lvl1 harvester on each of them using aggressive and harmfull dig stanzas. I think that would satisfy the minefield part, granted it would be a timed mine and not a proximity mine. It's the best I can come up with on such short notice though, I am open to suggestions myself
