Lost 1 min to insta blood moon in Calamity.
Insta blood moon happens due to run out of memory. I actually got it in many runs and it seems only happens in good runs. I guess bad runs have reloading save files with deaths or mistakes and loading save files clears the memory problem. There is an alternate Naboris route which uses loading a save file and only a few secs slower. It probably solves this problem.
