I am playing a game using 1.3 Beta 3X. When I have a high amount of research and could potentially discover multiple cheap advances in one turn, I still only seem to get a single advance with no "carry-over" to the next advance on the tech tree. However, the surplus seems to get banked somewhere, because I am still getting new cheap advances on the next turn even if I turn my tech spending to zero percent.
Is this a change in 3X? I also put all my game settings on Random, including Tech Rate. Could this be a Tech Rate thing that I was unaware of?
Just so you know, I like the "banked" research surplus better than having the research carried over to the next tech in the tree.
