Invincibility after defeating Dreamborn Terror

[Bellkatze]

After defeating the Dreamborn Terror, dying seems to be impossible.
Tested, in order, at Vulture, Jawcrab, Desert Watcher[imgur.com], Amalgam[imgur.com] and Giant of Eyes[imgur.com] in a single playthrough.
(my brain only fired after the first two to make screenshots already)
Intentionally trying to die does not "use up" the bug, neither does warping out of the boss arena or teleporting via Surrogate.
Dying to regular enemies[imgur.com] or enviromental hazards[imgur.com] is also not possible.
Dying to instant kill hazards, i.E. spike vines, is still possible.
Dying to Dreamborn Terror was also very much still possible.
To fix the problem, restarting the game seems to be sufficient.

Bug discovered in NG+12, reproduced in NG+13

Thanks we'll investigate this and see if we manage to reproduce it ourselves. :)
May bump this if we end up having any more questions
