My explanation for why there are changelings in Season 3 when Chrysalis and her army presumably fell to their deaths:

Some changelings might live lives of peace in Ponyville, Manehattan, etc. Her changeling army was only the changelings loyal to her. Like in Mario, Bowser is king of the Koopas and has many evil Koopa Troopas working for him, but there are some good Koopas especially in the Paper Mario series. (which isn't to say all the changelings we saw in Seasons 1 and 2 were peaceful, some of them could have been sneaking around to get info on Equestria)

And when I say "changelings in Season 3", I mean duplicate background ponies, although there is also a theory about Doctor Whooves and time travel
