There is no legion world boss spawned this week. This is not the first time this happened.
I have world quests unlocked, I killed several world bosses, etc. I’m trying to unlock the druid color on cat form and thus have to kill 8 world bosses.
[Whine part] The “Improving on history” step took me 9!!! weeks because of the week lock on 5 year old raids and bad drop rate. Now to unlock more colors I have to do another at least 8 week long grind, but it seems this will take a lot longer or infinite time if the ones I lack doesn’t spawn at all in the rotation because of bug.
{EDIT} Using this cheat page: https://www.wowhead.com/world-quests/legion/eu I tried going to both purple markers (the left one on the map is wrong, the upper right one on the island is the correct one) and only when entering the catacomb the world boss marker appeared on the map. So still a bug since it doesn’t show on world map, but at least with cheating it can be found and done.
