Well, there are a limited number of automatic connectors. If, for example, you're trying to connect a tier 1 research to a tier 8, there's no arrow long enough for the game to plug in.It is possible (though I doubt it) that this changed in 1.03, but as I've done research tree experimenting in 1.02 I can definitely attest to it automatically connecting dependencies.Out of curiosity, where were the relative positions of the two topics you needed linked?
thank you, this help me a lot. It does auto make the arrows for me. I can get it to work now.
