has anyone seen this happen before were Arche Seleukeia conquers all the way to india baktria and parthia all of eygpt and nearly all of greece only epirotes left (barely)

i was playing romans (fog of war on) and i had just started a war in greece greek states of sparta etc already dead maks had exterminated them i went to war with the mak's sent 4 legions in (15 units in each) and began to conqueror bout 10 years and ive virtually conquered all greece except constantinople.

maks own a couple of cities around there but not much of a threat anymore. i stop and decide leave one legion to guard greece rest sent bk to italy for retraining, epirotes are allied to me at this time but are up north near segestica.

i decide to check the whole map to see what's there and too my horror the BIG grey demon has conquered all of eygpt india parthia 2 settlements left, baktria 3 i new eygpt was dead but i wasnt concerned i thought wouldnt effect me till the marian reforms or around about. and pontos was a protocrate an from what i saw the mak's had been holding them off at nicea but were bout to fall and as i looked i saw at least 10 full stacks heading towards constantinople O.o

and thus the romani Arche Seleukeia war begins once the maks are gone all out war rages and i just couldnt kill them so many stacks as i killed one stack 2 emerged and they wernet just cheap units i mean heavey and medium galore and i could only defeat 1-2 stacks before my 1 legion was completly exhausted and needed fresh recruits

during this war i had created an extra 5 legions to combat them thats 9 legions total but they werent all in greece at once as i had to constantly bring legions bk for refit and new recruits, sadly i slowly gave ground losing pella after 5 battle for it so many dead 2 legions wiped out and a 3rd barely enough left to make up 5 units out of 15 i eventually decide that giving my lsat remaining cities corinth sparta athens and a few others to epirote holding 1 city for myself so i could pull out and then give it away out of all the 9 legions 3 legions got bk rest ambushed on the way bk or destroyed epirotes eventually pushed bk and Arche Seleukeia owns most of greece

my last attempt to stop the grey juggenaut was to launch an attack agaisnt eygpt to draw their forces away from the italian region,

though i never finished it since my mothboard went bust and had to get new components wish it would happen again what a challenge XD oh and has this happened to anyone else? or had something like this happen with another faction?
