Hello, 

I do not know if this has already been addressed but i noticed that when i play with my friends (or sometimes even in solo) some quests in the lastest extensions, namely the volvano forming quest in the early game tend to be based on the host of the game only. 

As i usually am said host the volcano formers appear close to my regions making it impossible for my friends to even compete in that quest. 

perhaps it might be due to me being the only oen having the DLC with the quest but i still find it a bit unfair for them.
