Thank you for reporting.
If I understand correctly there are two issues you mentioned
- No blood moon zombies spawning if you have a high level infested quest active when the blood moon starts
- No blood moon zombies spawning after you die during a blood moon
#2 is intentional to prevent new players from being stuck in a constant death loop.
#1 I could not reproduce, the blood moon zombies still spawned for me while I had an infested quest active (Dishong Tower). We'll need some more info on this one, please see below thread on how to file a bug report
