Nostalrius Begins - Quality wow vanilla realm (1.12)

I had 3 black lotus in my bank that I had bought over the course of a couple of weeks. Today I log in and they are gone. Anyone ever had issues like this? Is it because some were bought during that time frame when people were intentionally crashing the server to make more spawns? All were bought on the AH btw. Would really like a response.

I've never had something like that happen. Though, it could be as you said, related to the recent crashes.
