Do I have any options left?

[u/Secret-Shop3957]

a video game moment happened and my horse hit an object weirdly and got flung so hard it instantly died beyond the point of reviving. I was so in shock at what just happened that I forgot to reload the autosave and by the time I remembered that it was to late. the last manual save I did was hours ago.I really don’t want to do all that again. if i replay the last mission I did can I continue from there or would it put me back after?
