With it happening after Annie was already stored away underground, Eren recovering, Erwins interrogation being finished and the authorities already starting to question the other soldiers (-> Jean and Armin) it must have been an hour or more since the fight. More than enough time for civilians to come back to check if their house is still intact, unless they are barred from doing so by the military police cordoning off the area. But if they didn't see the Titan in the wall, why would they have done so in the first place?

Unless they rewrite the current "ending" back to the timing of the manga, they'll certainly have to adress this problem somehow, because the civies would spread that kind of news like a wildfire. And considering the uproar the anime invented for information about Eren leaking, the revelation of Titans being inside the wall being made public would be catastrophic.
