Sorry but i dont find something related to this anywhere so i dont know if it is a feature or a bug. The thing is that when i get damage for something, my psi energy goes down. Sometimes, if i am sorrounded by creatures i cant use the psi caster because it stop the psi regeneration too. If someone can say something about this it will help.

Maybe im idiot but i dont find nothing about that in mod options in the main menu or en in the folder of minecraft

Could have sworn there was an option for it. You are indeed supposed to love psi energy when getting damaged though.

Check your config as it's something you can change iirc

ok, i notices something new, some times i dont know exactly why i lost psi energy even with nothing equiped or activated, this is weird
