Turn 0 -- 1300 AD
Everything looks good...might be a long interturn if Carthage does attack. I upgrade the Pike in Dyes Peak to Rifle, just in case Malaca sends troops in that direction. I bring a whole bunch of Sipahi from Byzantium to outside Cumae in order to assist with (hopefully) dealing the killing blow to Rome next turn. I see the Tecs are in an MPP with both us and Carthage, so yep, let's hope they attack us first...
Oy, there's a ton of naval activity, and Arabia is nice enough to take out the elite longbow with a swordsman. Carthage withdraws its troops
Turn 1 -- 1305 AD
Syracuse riots; I hire a taxman.
Assault on CUmae. We lose a Sipahi, but defeat 3 rifles and a longbow to take it. I install a new governor in order to make it easier to get troops to Hispalis (which may be impossible anyway). I defend it with wounded troops; hopefully it won't flip before Hispalis falls (I think Rome is last in the turn rotation, so unless the RNG is unlucky towards Carth...)
Yep, we can't reach Hispalis, blocked by an Arabian Sword and Carthaginian Cav.
Sivas is built, Library ordered up.
I've been working on the railroad, all the live long 5 year period...
IT: Aztecs declare war on Iroqi...for a brief second, I thought our MPP had been tripped, but no, it was a straight-up assault.
Carthage is unable to take Hispalis

... however, they land a gazillion troops there to try again next turn....hrmmm, we're going to need to get our Sipahi ready for that stack.
Turn 2 -- 1310 AD
We build Intelligence Agency in Uskudar.
More railroading. Carthage and Aztecs have Steel, but Iroqi do not.
140gpt+1125 to Aztecs for Steel. I trade Steel plus a couple lux to Iroqi for Refining. I trade Indus+Elec to Arabs for Communism and all their gold. Tech parity is achieved.
We have 3 sources of Oil hooked up, and at least 2 more not hooked up.
IT:
Carthage takes Hispalis, the Romans are no more.
We're at war with the Iroqi! Our MPP with the Aztecs is triggered! Carthage declares war on the Iroqi as well!
Ok me boyos, decision time. Technically we don't need to attack Carthage at this point, as Carthage, Iroqi, and Aztecs were a pick 'em...plus everyone has already ganged up on Hi. What do we do? Do we risk a World War where everyone is fighting everyone ('cept Aztecs v Carthage) and allow Arabia to take the lead?!? Do we just clean off our continent (hoping the stack of wounding (not big enough to be considered stack of death) in Hispalis can be easily dispatched) before going overseas?
BTW, our reputation is shot. I wasn't thinking when I made the deal with Iroqi (i.e.

)
Here's the save in case anyone wants to look at it (it's the beginning of the turn):

OMT: Did I accidentally do an exploit?

Do I need to replay my previous turn and not do the deal with the Iroqi?
