Citadel bosses not phasing

So I am having three major issues with Citadels right now.

1. Why are the bosses not phasing when they are pushed down to 0 HP. Just had a fun experience with Doryani where I pushed him to 0 HP within a few seconds. For some reason do he never phased just kept on using abilities until my caracther died. He kept skilling for well over 2 minutes obssesing over the wheel with beams. Iron Citadel has had same issue never cost a death but Ogham will just keep on fighting with no HP for a long time without phasing.

2. Just realised they are not rentriable. Which is bad, let them be tried again but perhaps without the crisis fragment drops. It is specially annoying when such a thing as not phasing or server DC can cause you a Citadel. They have to much value in a to fragile game to not have them be something you can simply reentre if the game does you dirty cause let's face it great game but lots of things happening now in the early access that are obviously not intended, such as damage taken before visual effect, not phasing, crashes etc.

3. For gods sake my Iron Citadels are completed. Yet the map insists on saying map failed. I have the rewards so that's fine. But seeing "map failed" on the map device when it isn't, is annoying af.
