Since the 1.49 update the research order has been changed, it is now somewhat chaotic compared to before. You used to have technologies that fed into each other relatively close in the order. E.g. Superior Armory used to be at the top of its column, which fed into Treant Promotion, at the top of the next column. Now Superior Armory is at the bottom of its column, feeding into Treant Promotion which is still at the top of its column. So the lines between these columns now cross (stack) needlessly and make it a mess to follow. Another example, Dryad was top of its column, now it's moved down 4 places to the bottom - It feeds into Cerberus, which was at the top of its column and it is now in the middle, etc.
