After wearing Gobber2 set which feeds the player and removing it the food values does not go down and after death health keeps scaling by +2 hearts. SoF clearfood command does not help either. The only solution that I've found is:
disabling Gobber2 set bonus in config
disabling SoF and entering the world
re-enabling SoF

Let me know if I should report this on Gobber2 side instead.
