Nostalrius Begins - Quality wow vanilla realm (1.12)

Hi, I'm not able to find a place to report a bug and i can't report on the bugtracker so I'm reporting the bug here. So the bug is that I drop a item "Hardened leather shoulderpads" level 32 on a "riverpaw gnoll" level 11 in westfall.

So I hope the bug will be report and fix, thank you.
