Hi !
I have also had issues with the Wandering Shamans. There were a few spawners that had them in the Valley of Eodon on my shard.
Waiting to find what is wrong about them, I have just removed the WanderingShaman entries in those XMLSpawners.
What is weird is there is nothing wrong in the WanderingShaman script. Maybe it’s linked to the map. They all spawn in the internal map.
An easy way to delete them all is by using the [xmlfind command. Just look for the WanderingShaman type. It will return your 380k shamans in a list. Select them all, and hit delete.
You will get a freeze for about 5-10 minutes (it should delete all the items linked to them if I am not wrong).
Also, don’t forget to remove the entries on the 8-10 spawners having them. Or you’ll get the same issue in a few weeks.
At least, until you find how to solve the problem about them 😉
Good luck !
