I was managing my researched technologies, and I went to research power generation. I clicked on it, and it automatically skipped to 91% and continued to research until it was finished. I had not been researching it before, it just skipped to 91% right away. I thought it was just an error or something and reloaded the app to see if it would reset it, but it didn't. This isn't a bad thing, obviously, but I thought I might post this for people to see.
