I'm not sure what's going on here.
Text effects (like "fade-in-out" and "shudder") no longer work for me with the latest version of Harlowe, at least for my own games. Additionally, the "fade in" Harlowe naturally does on each page is no longer happening. The whole thing has become completely static. When I go back and play games I published to file before the new version, these effects work fine.
Oddly, the "blur" effect still works. Basically, anything that would animate the text at all no longer functions.
My main browser is Firefox, but I tried Chrome and it's the same issue there. I'm attaching the game I'm working on so you can see for yourself. (Just the first few screens should be enough to see the difference.)
