Thank you for reporting this, and has been noted. A confirmation from another player, when we get the game up and running, would be greatly appreciated.
Yeah, before the game went down the mist terrain that the spell creates didn't work. The visual effect of mist forming would be there, and for the correct duration, but the mist's effect was bugged (i.e. nothing stealths in it). I'll test it out once the servers are back but I expect it to still be bugged.
i wanted to confirm that fog of ancients does not stelth champions both enemy and frendly. tested pve and pvp
