@ZOS_Kevin since we can't reply in the Patch Notes and Hotfixes section, I'll just post this here...
As per the hotfix notes you posted (screenshot below), the Archival Sacks of Provisioning were fixed as well. But what's not apparent is whether they've been dropping at a higher than intended rate the whole time, or did they see a bump at the same time the Jubilee Reward boxes started dropping and were simply lowered back to right before Jubilee levels. Could you please provide some clarification on this?
