So, for my PvP arena I used to have a command:
effect @a minecraft:saturation 1000000 20 true
... which runs constantly to keep the hunger bar full, so that natural regeneration slowly regenerates health.
However, if do it in the latest snapshot, this effect breaks with the new food system and instead it regenerates health at a ridiculous rate (1 heart per second), even if saturation is at level 1.
Is there any way I can keep the hunger up, but with a lower regeneration rate than the one that has been introduced in the 1.9 snapshots?
