"Also, this morning, we launched a big change for Underworld!"
there is a bug with the underworld quests, not sure if it is because of this change or lasts for a longer time already: both quests "Get 500 Hero Pieces" and "Get 1000 Hero Pieces" can not be done because the promotions do not count if you do them (i used the random squad promotion). otherwise it is nice to see that the underworld was updated, i like the new map design.
