Recoup and damage redirection to mana

Currently I'm running a chaos recoup chronomancer sorc and I've been trying to make use of the recoup mods. I'm currently sitting at about ~70% life recoup and 90% mana recoup with equipment and passives. I am also taking damage redirection passives and equipment and am sitting at around ~40%. Combined with Eldritch Battery the idea is to split damage between health and mana and then recoup it.

This is not working as it seems it should be intended and I am not sure where the problem is. I have experienced a number of issues. Such as neither Life or Mana recoup working as expected or not at all. Example would be that the life and mana recoup numbers are not matching the amounts expected for the damage taken. Or they are not functioning at all, giving me no recoup.

And damage redirection to mana almost never works. Especially for big hits it seems to almost never redirect the damage. I have ran several tests and purposely took big hits and my mana never moves. The damage goes entirely to life, which in a lot of cases kills my character.

just chiming in to say I encountered the same bug - mind over matter works but partial damage redirection to mana via the passive tree not. It somehow even seems like you take more damage to life when picking those nodes.

I don't have the exact same issues but in the last week recoup hasn't been working consistently. Sometimes it works for life recoup but mana recoup doesn't work at all. The 3% ES recoup node is working.
