For weeks I have been trying to fix a problem I am having with my dev server in-game art library - both my library and premium assets do not show up. I recently found a fix. Unless I open a game, mostly two games, in the production server first, then open up a dev server game, the art library loads. This happens with all of my dev server games. Any production server game/s will work to allow me to open any dev server game with a properly loaded art library. Version 55.0.2883.87 m Google Chrome is up to date.
