I've been getting Photoshop CC to crash consistantly when I try to generate scaled-down pngs from a layer group. If I have generate image assets on and change a group name to "50% name.png", Photoshop instantly crashes. If generate assets is off and I change a group name to "50% name.png" Photoshop does not crash until I try turning on generate assets, and then it crashes instantly. Trying "50% name.png, name_full.png" also fails. This has occured in different files. It does not happen in every file or every time, but it happens very often.
