This is a "Fixed" version of this mod: https://modworkshop.net/mod/17557 by SWEtea
What does "Fixed" mean in this case? It means that the original mod, mentioned above, had incorrect texture size.
I fixed it by taking the original green health circle from the game files and simply recolored it with the same color from the mod mentioned.
It had no licensing so I decided to re-post it myself.
