Well I'm sorry to hear that. It probably doesn't make a difference to you now, but I stored the few NQ stones I had on the NPC while hoarding Ghastly Stones +2 to trade in for Obsidian Shards to buy NQ stones. You could also easily get enough shards just from the Green Pells we've been getting.
When I worked on H-P Bayld and Alex there was no way I could function if I didn't have a mule to store them. Incidentally, all the Gobbiebag and Mog Safe expansion items are on sale from in your Mog Garden right now.
Here's hoping SE throws you a bone.
