Pre-flight check: MM for a bunch of merchants to improve the economy, we're running positive @40% sci now

I'm all for war, but you can't completely neglect your economy. There are some real

builds going on here, rax in cities with no production, theatres before courthouses in areas where we're losing 10+ gpt in maintenance when we can run Artists for border pops. Capturing the Romans is going to bankrupt us before we reach domination, and Lizzies going to have Redcoats before we think about getting over there. Before sending all of our army to Rome (the right call, don't get me wrong) we should have been sending all of our workers to Spain to chop in courthouses and the FP, in addition to missionaries to spread Confusionism, which would have taken care of the culture problem while also adding much needed coin to our coffers.
Also, why are our bombarding cats non-accuracy promoted?

More importantly, why are they bombarding with no promotions at all?

I don't mean to overcriticize, but WTH happened to this game?
I don't think I can both fight the war with Rome and salvage our economy, and I have no choice but to press on Rome, so here's hoping I'm not disbanding units in 10 turns. I hit enter.
IBT - We kill a cat outside Pisae and lose a Camel Archer outside Rome. That stack outside Rome is going to take a while to take the city. One cat.
1305 AD - Pisae falls without incident.
IBT - If the AI were worth anything they'd have retaken Pisae, but we luck out and they don't. We do lose a mace.
1320 AD - The RNG is friendly to us, and we sack Rome without losing any units, including a Camel Archer defeating a City Garrison III Longbow without taking any damage

Hey, I'll take it.
How about two Roman Capitals in one turn?

The Roman Capital is moved to Cumae after the sack of Rome, and this happens:
IBT - Rome puts together a decent assault force at Cumae, very nearly lose it as I only was able to move two units in. Probably should have waited for reinforcements, but I think we're ok now.
1325 AD - I think Rome is toast now, just a matter of how long the shuffling really takes. I've now got a semi-decent workforce over to former Spain to start chopping courthouses to salvage the economy. Vicki switched to Mercantalism. Send Alex fishies for 6 gpt, mo' money.
1335 AD - Greeks take Gao from Mansa. Mansa will probably be easy pickings as a next target after Alex is done softening him up. Shuffling troops, Antium should fall next turn if all goes well.
1340 AD - Gunpowder in, start Banking. I suspect Vicki will beat us to the free merchant at econ, but Banks will help with our economy anyway. When it comes in, if the free Merchant is still avail, I'd grab that. Otherwise, I'd head toward Chemistry, Grenadiers will probably be enough to take out Mansa for the win. Have some terrible RNG luck @ Antium, it'll have to fall next turn.
1345 AD - The Heroic Epic is done in Beijing. I'm not sure if it was the right choice, its not the production city it once was, but it needed to be built somewhere. And the third Roman Capital of my turnset falls.
Trade Vicki Philo for Banking and all her gold. Set research to Econ in 10 at a defecit. WW has reared its ugly head, we're up to 4 unhappies from it. While Rome is spent, still probably 10 turns or so from its total capture.
Units now in position to take Antium and unnamed Roman City in 2 turns. I also have a CA outside a city they dropped on the Spanish continent, it may or may not be enough to take it, but theres a mace on the coast that I have a Galleon swinging around to pick up that can be there in 2-3 turns. May be best just to wait til its there to reinforce to leave no doubt.
I've moved a bunch of workers to Spain, I'd chop the hell out of it (Don't worry about longterm, we're not looking for space here.) Courthouse finishes in Barca next turn, I'd immediately chop out the FP. We just need enough research juice for another 2-3 techs really, Chemistry then an upgrade spree then take out Mali with Grenadiers. That plus a few settlers plopped on our 3 continents should suffice to give us Domination. We're currently just shy of 40% of land with Rome and Antium still in revolt. Make sure they have as many artists as possible hired to pop borders, then put them all to work after that. Keep an eye on econ, if we lose the chance to get the great merchant, switch to Chem. I'd start a GA with the merchant when he comes, but sending him to London or Athens for a trade route isn't a bad idea either. Don't neglect getting some settlers to fill in the gaps on the 3 continents. Every green tile there is one less tile we have to grab in Mali. Hell, might also be worth sending a few settlers over to the unoccupied islands, we might be able to hit dom without another war.
Theres a bunch of galleons outside Beijing, and a full Galleon outside Rome. The galleys outside Spain may be worthless, might just be easier to build new ones on the mainland than upgrade those to Galleons given our economic realities.
Anyway, here's the save:
