On Wave 5 (last before the break/pause) I got one of the Ox…birds (don’t know the proper name) “of focus” with an ability to resurrect two seconds after death.
I killed the boss (first time) and everything looked like the waves were completed - barrels, stash and wandering blacksmith all appeared as expected.
THEN the boss respawned and it just looked weird to fight him for the second phase.
My expectation was that I’d have to kill him for phase 2 before the wave was considered complete. (As it was the last in a set of 5.)
(Going back to the grinding again now…)
