I finally managed to get it done today, that was pure nightmare experience. No raid boss is as tough to get it done as The God of Cows. RIP to players who still need to get this done, I wish you the best of luck with finding fresh map instance. I camped so hard to get it done that it gave me a little bit detrimental effect on my mental health due to frustration, lol. Your chance might be after patch day - if the patch will drop not during palawadan then patch the game immediately when patch drops and go to istan. If it drops during palawadan then the fresh instance will be bugged, but then if 2nd map instnace spawns outside palawadan hours then it will be unbugged.
