I created a bunch of artboards and put logotypes (word logos) in them, exported each artboard as separate SVGs, closed the file. When I opened the file the next time, only my first artboard still remained but all my artboards I created after that were gone. This is disruptive because I need to keep the placement of all of the graphics in those artboards consistent as they are going to appear on the same baseline in our product. This is not the first time this has happened to me! I can't attach an image as the content cannot be public yet.
