Thanks all for continuing reporting. This is still getting active work done on it; we were able to resolve some issues, but (clearly) this is still affecting players. A small update was shared yesterday, for anyone who may have missed it: Lost Ark Update to Top Issues - March 2
Ongoing Store Issues and Missing Product Inventory Items
Store issues have drastically decreased with last week’s maintenances, but this is not yet fully resolved. We are still working on making improvements to these systems over time as we roll out additional patches and maintenance, and we understand that some players may still be having trouble collecting certain items and packs from their Product Inventories. We are still working to fix this on a broader scale, in the meantime players with any “missing” items may have success getting them to appear sooner by logging into their respective server during an off-peak hour.
