You're fine. It could just be something on my side. I'll keep looking for anything that my computer could be doing.
Also, is there a way I can access the JavaScript console, as the game error suggested? I might be able to make enough sense of everything to find my failed "uncaught loading data file," or whatever else might be happening on my end.

Opening this brought me to a blank page with nothing but the error message that I think is the root of it all:
I assume my computer is the "anonymous caller" here. Either that, or the game is showing up as anonymous. Either way, something's trying to access storage, and it can't. I cleared all cookies twice and made sure nothing on my computer was different from when the game was working. If it's my computer suddenly blocking the game from accessing cloud storage, is there a way I can make my computer allow the game to?
In order, from top to bottom, the links sent me to these spots in (I'm assuming) the game code:


is "Module.locateFilePackage" the file data the game is trying to get?
