I’m unsure whether this has been fixed, as the servers have been behaving so far since the last service disruption (and maybe a silent patch was applied when the issue was resolved).
This is a repost of a previous closed bug report: Can't publish a place, nor download *local* copy
which I believe was incorrectly closed (moderators likely assumed it was a more-or-less identical bug report to the dozens of other reports on the service disruption).
It’s inevitable that Roblox servers are going to fail again - which is perfectly fine!
What is not fine is the fact our ability to download local copies also fails. Whether this is a bug or a feature is beyond me, but shouldn’t these systems be independent from one another?
