Was Max hp on level up for BG:T removed?

Because I'm not able to find it amongst the tweaks o.o

 

It's not in Eetweaks, it's in Tweaks anthology: https://gibberlings3.github.io/Documentation/readmes/readme-cdtweaks.html

Well, thing is, the EE has in game option to do this currently ... v2.5 or above.

BG2 had this ... as a hidden feature in the in-game difficulty settings... as if you set it to easy, you get max HP at level up. This is not of course a re-versive(aka it doesn't give you more hitpoint if you first level up in hard mode and then reduce difficulty).

Tweak... doesn't matter to me, I never play the game anymore.
