This is a singleplayer world in 1.16.

I didn't think of this case at all, I'll get around to doing it in the coming days. Thanks for reporting it! The issue probably happens in every version, since I didn't touch the tab overlay.

Glad I could help! Would you be adding this to previous versions as well or just 1.16+?

Most likely 1.14+

That's good, thanks.

This should do. I only did 1.15 and 1.16 because I forgot that I already deleted the workspace for 1.14. I'll also look into doing the same thing on forge, if its even possible. But I doubt that it'll be possible without some hook though, so its not happening if thats the case.

Also some additional info on what I did. Since you can only access the "score" value, I couldn't make a separate renderer for absorption and for the health, instead the hearts are all rendered with the colors for the hearts from the hotbar. I might add a separate config option for those hearts in the future.

Sadly, after updating the mod (3.6.11) the issue still seems to be present.
Also when the player's health reaches 44 the game stops rendering the hearts altogether:

Which would make the health overlay in the player list redundant when players have 44+ health.

Oh, the feature works only in dev. Seems that something is broken with mixins/fabric. I'll look into it.

Alright, it should be fixed now. Tell me if it works when you have the time to check it out

Yeah, It works like a charm, thanks!
