Recovering Missing Pages in Relume: Version History Guide

Hey everyone! Relume newbie here with a question around version history. ⚒️ I'm working on some wireframes right now and Relume kept freezing in my browser last night. Everything looked fine though after refreshing the browser but when I opened my project today I can see that there are multiple pages missing from the sitemap and wireframes. Is there a way to solve that? Is there a version history where you can go back in time and find a saved version that includes the missing pages?
