I have successfully created a mod that rearranges the Ancient and Classical Era technologies, giving them a new logic for their prerequisites. The tree functions as it should. But those damn wires are being drawn every way they're not supposed to. The wires are controlled by some automatic generator, and it's fine so long as every tech requires only techs from the previous X-coordinate, but ask for one step over, and suddenly they break and recurve and do all kinds of nonsense with no basis in the logic. I'll get a picture up (can't right now), but, for instance, I've redesigned Horseback Riding out of existence, reassigned Civil Service to require Writing and Currency, and I lined up Writing with Civil Service. Nothing in the way. Should just be a straight line, right? But as long as I do things that way, there's a broken wire out of Writing that draws in the direction of Theology. My question is simple though. How do you get the tree not to fuss with you? I am modding within the Community Patch. edit: See in the files... Mining has a tiny part of its wire missing - it's even weirder than the other glitch. I'll also provide the civ5mod for troubleshooting.
