I'm really liking SpriteStack. Sadly it seems to have broken on my system since last update. The "save" button turns to a highlighted pink-orange and does nothing on click. Export to VOX button is not highlighted but also does nothing. I can't save nor save as older files, but I can open them.
I'm lnxpnk in Steam. Would appreciate a fix.
I can confirm the bug both in ubuntu 18.04 and POP! OS 19.04
