Hello everybody! I can't for the life of me figure out how you do even basic character sheets without the previewer for custom sheets working. Across three different browsers (chrome, firefox and even edge) the css just doesn't get rendered half of the time. Now it works, then it doesn't. This bug is over a year old. How do you get around this? I'm so sick of refreshing, reloading, lauching the game, clearing the cache and doing all kind of nonsense just to get this to work. When I look at some of the complex, fantastic sheets people are putting online, I really wonder what their setup is. One thing seems obvious to me: they don't use that previewer. So what DO people use? Is there a way to develop this offline and inject the roll20 scripts/css to get a realistic preview? Somewhere in a bug thread someone mentioned to have set something up using gulp, but gave no details. Any help is appreciated.
