Sunwell quest to unlock void elf or whatever is that after complete every single achievement and loremaster of Suramar and Legion etc. U need to go with npcs to Sunwell instance. Portal to this instance make you infinity loading screen. Cannot be completed without group because when you use portal to this Sunwell instance without group you are kicked from this quest instance scenario after 5 second because you are not part of group…whatever whole video cinematic sequence before this was followed by camera under textures of city. Very funny…+ when you finally get trough loading screen it will port you back to Silvermoon with "Transfer Aborted: Instance not found. xDDD
Sometimes it will automaticaly change settings of instance in chat to normal scenario but after using portal it make automatic kick with chat msg You have been removed from a group - without have group before.
AFTER COMPLETE NORMAL VERSION OF RAID SOLO IT START WORK
