That explains why daily tournaments have such low scores :) There is a workaround of course - use power ups (I was able to kill the 655k HP boss in one go this way). Alas, whatever remedy supports provides to you - you can't win in this event unless you spend $300. Which is the actual bug you should be complaining about.

P.S. The issue does not repro for me, I could fight the same enemy multiple times.
