I've been trying out the sorcerer with patch 6 and have come across two things that are probably bugs.
The first one is using the twinned metamagic with the witchbolt spell. When both of the projectiles hit their respective targets and both the enemies survive, concentration is lost and the link doesn't form (or is lost on both). I don't know if others have been experiencing this and is a bug or if it has got something to do with my PC. I also tried to twin a friendly concentration spell (enhance ability) and that did work. What I haven't tried yet is using a different offensive concentration spell so I'm not sure if it's just the witchbolt spell or the targeting of enemies.
The second thing I found was that the spells you get from the dragon ancestry don't offer the option to use it as a level 2 spell after unlocking level 2 spells (I've only tried witchbolt and burning hands). I don't know if this a bug as well or if it's as intended.
Has anyone else been running into these problems? And if so, has anyone found a fix?
