After getting it as a quest reward I used “Fiery Festival Brew”, “Handful of Summer Petals”, “Toasted Smorc”, "Midsummer Sausage in Zangarmarsh, Outland. Then I mounted up and made my way to Blade’s Edge Mountains, while flying with my mount the alcohol effect of this brew (I assume it’s about the brew) started my character to change directions almost every millisecond, controlling any movement my character going kept crashing the game for like 7-8 times in a row.
I never experienced this type and intensity of crashing while under the alcohol effect in-game.
