0.9.6 Mortem Dagger not sharing health increase

So this is likely a rare case, but when I cast Reincarnation on my monster with Mortem’s Dagger, rank 75, he triggers his Woe and Meat Bomb traits, and more than doubles his health usually, but none of my other monsters gain any max health.
It appears to work fine in most other cases, however, so it might just be because he died?
