This snapshot with the bartering trade system with the piglins removed crimson fungus as a trade item which makes them no longer renewable. The previous snapshot had the crimson fungus renewable. Now that I can't make infinite crimson trees, it means crimson stems and all of their variants are no longer renewable. Please make them renewable again. It can be tested out by throwing a gold ingot to a piglin or looking at the Minecraft Gamepedia page.
Update - soul sand is no longer renewable as well but both soul sand and soul soil should be renewable unless it's for balance purposes.
