I have been creating a website using thimble and when I logged in the other day to continue working on it A LOT of the changes were gone. The index.html page had reverted to the default ("Welcome to Thimble") and all of the styles that I had worked on were gone but all of my added files (images mostly) where still loaded just not used like they were suppose to be. I left the page and went back in and then some of my website returned (not to the most up to date version though). I would like help with restoring all of my work back to the most recent change.
