Based on that following thread https://us.forums.blizzard.com/en/d3/t/error-loading-the-hero-code-395002/54458
We can see that a guy posted that issue about 7 days ago so Blizzard is already aware about that by the fact that this guy also sent a ticket at Blizzard 7 days ago as well based on what he said and nothing happened since then because the issue is still persisting at this day. I guess that it’s still not enough to make that a priority? What are the requirements for an issue to get resolved quicker? How many days of downtime does it take to justify being able to ask to fix this issue?
Thank you
