Good evening, gentlemen. I just unlocked the Fintlock technology and I'm currently confused as hell, trying to understand if something is seriously bugged on my side or not.
I'm looking forward to upgrade (with gold) most of my medieval soldiers into the new units that are available : Line Infantry (Mamlouk) and Bachi-Bazouk.
So far, Line Infantry seems to work as intended : I can upgrade almost every unit into it, but it has a hefty cost (around 500 to 1000 gold
per unit). It's wild, but I can understand the cost : it's a big upgrade, I'm making something like 800 gold per turn (with

at 0%) so it's not like it's totally impossible, and obviously, as I play with the option that increases units cost the more you build them and have 14 cities to defend, the

increases must it hard.
What I truely don't understand are the Irregulars, the Bachi-Bazouk.
First, they are dirt cheap. I understand that Irregulars are "meh" compared to regulars units, but they cost a flat 10 gold per unit. No increase at all, I can upgrade my whole army for 150-200 gold, which seems weird looking at how that is not even a fifth of what a single Line Infantery would cost me. Is it intended that this is only a token price and that everyone unlocking Flintlock is suppose to drop all swords and go full rifles on the very same turn ?
And now, for the (perhaps ?) buggy part : the Saqalibah, my National Unit, seems to be the only unit that see it's upgrading price increase the more Bachi-Bazouk I own.
When I have no Bachi-Bazouk, the Saqalibah -> Bachi-Bazouk upgrade price is the same as for everyone else, a flat 10 gold pieces.
But if I upgrade my others medieval units first, and then try to upgrade the Saqalibah once I already own a few dozen Bachi-Bazouk, suddently they need more gold to be upgraded. And it seems to follow a logic : the more BB I have, the more pricey the Saqalibah upgrades is.
It won't really ruins my game, as the obvious counter is to just upgrade all Saqalibah before I start upgrading the rest of my units, but I wanted to check how normal this is (and knowing if there is something wrong with the upgrade price and little me upgrading my whole army for 150 gold is cheating or not

)
