Summer Wrote:I remember someone having a similar incident with their guild storage. Don't know how exactly that was resolved, but I'm pretty sure it was resolved relatively painlessly.
Gonna chime in because me thinks Summer was referring to me. Had similar problem just like you losing stuff, except it was on a larger scale with all the ~700 items in my guild storage, which included many cards, gears and other items lost. We couldn't find out what caused the items to disappear cause there was no sign of people stealing items or anything. In the end, Garr (iirc) managed to recover all of my lost items by next server maintenance.
You should definitely send in a support ticket whenever weird things like this happen, and you did the right move considering how recent it was to the incident. Mine however might have took a lot more work for the GM team to recover because I didn't know when it started disappearing and there was so many items too xD
Hope you get your items back as soon as possible~
Edit: Some rephrasing.
