Nostalrius Begins - Quality wow vanilla realm (1.12)

Hi,

I can't pick up the last part of the infernal quest chain from Impsy in felwood. I read somewhere that it might be a problem with the version we are playing, but we are playing 1.12 right? So, that should not be a problem?

I want my infernal :3

Cheers,
Storluffarn

Technically, no.

1.12.1 client, but the server features are enabled around 1.3.
