Do you uave hyper triggers? If not, add them.
Also, I dont know if this would help, but try it out because I dont really trust switches

Instead of putting switches just put death counters:
Trigger 1Condtitions:- Deaths of 'unit' is exactly 0
- Switch Level 1 is set
Actions:- Do cool stuff.
- Set deaths for players to 1 for 'unit'
- Preserve Trigger
Trigger 2Condtitions:- Deaths of 'unit' is exactly 1
- Switch Level 1 is set
Actions:- Do more cool stuff.
- Set deaths for players to 0 for 'unit'
- Preserve Trigger
That might work. I'm pretty sure it would.
