The event turns Porto back to Portugal, even if it is already occupied by french troops
The result was that I lost an Army stack and three Corps that were having a nice vacation there after a succesfull (and very ahistorical) amphinbious invasion, they just disappeared
Of course I went back one turn and ordered everybody out, the event fired again a couple of turns later and all was well, but there should be some way to avoid this kind of situations, maybe if every major city is taken, the event shouldn´t fire at all (not counting the fact that in my particular campaign the UK is completly occupied too, I guess Wellington came all the way from India, together with armed portuguese expatriates
)
