Effects of continuing after a total party wipe?
Solution 1:
The option "Continue" just means "load the lastest save". Dragon Age Inquisition uses the autosave function which is triggered if you get close to hard fights like bosses and at some random spots that i dont know. To answer your question - there're no negative consequences for loading your last savepoint and it seems that you just triggered an autosave just before your party wiped out. If you look in the menu under "load" you should at least find one autosave.
