The sheet in question is for Sword World 2.5. One of the google fonts suddenly disappeared from the sheet. It was being used in roll templates. Looking at the rendered source, I can still see the other font load, but not the missing one. Here's what the missing line looks like: @import url('<a href="https://fonts.googleapis.com/css?family=Jim+Nightshade&display=swap" rel="nofollow">https://fonts.googleapis.com/css?family=Jim+Nightshade&display=swap</a>'); If I try loading the sheet (directly from the copy in Roll20 github) in the sandbox or as a custom sheet, it works as before. So, it seems like the font is being filtered out at runtime for some reason. I tried adding a space between it and the other font in case something weird is going on, but no luck. As a workaround, I added one of the standard Roll20 fonts as a backup font to the css. But that kinda of sucks, and really I'm just curious why it suddenly stopped working live. Anyone having similar issues?
