Attempting to save project opens the save as tab 0.4.8

Whenever I'm working on a recently opened project and go to save, it brings up the save as tab, asking me to save instead of the usual saving as normal. I've experienced this bug since updating to 0.4.8. The same menu pops up anytime I attempt to save something. The program saves the project, but the tab opening every time is a little inconvenient.
