So I finished a game after removing the other conflicting mods, and it worked fine. So I guess that was the problem, on my end.
The Russian naval units and the new Stealth Fighter model look great! I’ve been having a lot of fun with the marine units especially, though one thing that did bug me was that they don’t start with the amphibious promotion. As of now they only start seeing “marine-like” benefits after they reach a promotion, which can be a little difficult at first since they are a tad weaker than other units in their respective eras, unfortunately. Can this be fixed easily?
On another note, shouldn’t the mid-level marines use allied weaponry like Thompsons (like in Civ 5) or at least rifles instead of the German Stg44s? The Germans didn’t have as great a marine force so much as the US Marines, Royal Marines, or the Japanese. Sorry to be nitpickey, just trying to offer feedback. Keep up the good work!
