How to determine if new plat pack is replacement for old missing one or just the extra being handed out?

I previously lost a platinum founder’s pack because when I opened it the shop was unstable and it vanished without granting me any items. Today I notice there’s a plat pack in my product inventory–how can I tell if this is a replacement for my missing one (I had submitted a ticket) or if it’s the extra one that’s being given out?

Have you checked the status of your ticket? If it hasn’t been updated or closed it’s likely the extra one.

You were right; it hasn’t been updated so it’s as you said most likely. That begs the question: where is the original pack? If they can poof these into existence they should be able to check for who opened the initial packs and didn’t receive items.
