Hello, we are playing in 1.18.2 and are having an issue with regen added by scaling health for origins that are set up to specifically have natural regen turned off. (specifically the siren origin from collection of singiro, an origins mod add on for forge). So I'm trying to figure out if there is a way to disable the scaling health regen rules and revert to vanilla regen rules (which work with the origins mod) or if there is a way to do this via datapack? Thanks in advance!

Heya, I know this probably won't help you anymore but for others like me that experienced this issue I found the solution:
Go to your Minecraft/Modpack installation folder and in the config folder look for the "scaling-health" folder. In there you open the "game_settings.toml" file with an editor tool of your choice (Editor/Notepad++/etc.). In line 260 the "#Settings for players" start, there you should find the regen config for players. Line 282 enables/disables the regen system. By default this is set to "enabled = true", change the true value to false and youre set.
