It still works on EU farmed around 15K Timewarped Badges now.
I should point out there was a pre-existing method to get multiple shots at 500 TW.
There are ways to monetize badges which are profitable but not spectacular.
Tried on EU 2:13 AM (again) Not working anymore for me.
https://eu.battle.net/forums/en/wow/...5692857#post-7 It's been hotfixed. No mention of any penalties or removing badges so far. Mine hasn't been removed yet.
Literally 10 minutes ago got another quest, so definitely not fixed yet (EU).
Does seem like it was hotfixed in US. Just tried it again after spending a day off. First run I got an ember (I did it 3 times last night) and then I relogged and did my second run and never received one.
Will update if anything changes.
