I’m not getting any boss powers after the update for the new season and the tab for the boss powers isn’t appearing either. I’ve defeated world bosses several times (didn’t die etc.), lair bosses and apparitions but I didn’t get any boss powers. After the update was downloaded and I went in, I saw that you can boost characters in Kyovashad. I teleported there, went to the optional quest that was displayed, opened it, and accidentally typed too quickly, so I confirmed something without meaning to because I actually wanted to boost a new character. Then I had to select the skills for the spiritborn, and I couldn’t go back etc. So I quickly canceled and quickly went into another character to see if the optional quest was still there for boosting, or rather the chest in Kyovashad, but unfortunately it was gone. I couldn’t even boost the spiritborn and then it was gone too, I think that’s pretty bad. It would be nice if they could fix that too 
So after the whole thing was over. About 10 minutes later there was a world boss which I defeated without any problems but I didn’t get any boss powers. I have lair bosses and apparitions but I don’t get any boss powers either, so there is no tab where you can see the boss powers. It’s pretty annoying because it’s more difficult to defeat tougher enemies after the session when the boss powers are suddenly gone. I also put a lot of time into the boss powers last session and created a special build for it, so I hope this is taken seriously and can be fixed as quickly as possible. I don’t know if it’s a bug but I can’t access the loot chest on the new character, or I have items in the spiritborn’s chest but they aren’t displayed for the wizard.
