Dark matter dice wasn't available for a while and I understand that it has been revamped (I miss the previous graphics so much :( ) but now all dice gets rerolled, regardless of whether or not they're selected. Not sure if the selected dice are supposed to reroll since selecting them shows HOLD but also the option says reroll selected but whatever. The game doesn't load at all on kumos so I couldn't check if that's the case there as well.
