In general, the Character Vault seems to always be slow. Often it results in a CloudFlare message but usually a Reload does the trick (though still slow). Today, the page crashed with the following message:
An error was encountered
Don't worry; it's not like you triggered the end of the world...right?
If you message us about the error, please give us the error ID below so we can look it up:
d3682024335148bf8521c15a6e8c6739
When I reload or navigate away and back again, get a blank page with the following message: An unhandled lowlevel error occurred. The application logs may have details. If you're wonder, I'm running the latest version of Firefox (86.00) on a macOS Catalina (10.15.7). Hope you this help.
