Just so you know, the smoothbore cannon has two versions one of which is called flipped..... and the game no longer uses it like that, because you can press x to flip it (i gues you know that but made som error in implementing it)
Also when playing conquest, currently the tier 1 research setting works like having a tier 0 (meaning you don't have any starting research) for me, and then tier2 works like tier 1 and so on, so i think you have it set 1 too high on all of the research.
