recent beta update has screwed lots up

after i just updated minecraft beta, i logged in and noticed a lot of issues

beef and steak have names like "item.cooked_beef" and "item.raw_beef" (or something similar)

my baby dogs head appeared invisible but the body was normal and appeared again once it grew up

when in creative mode, multiple items missing and many items replaced with skeleton skulls

cant sprint swim in water that isnt a source block, it acts like theres something in the way

horse armor doesnt appear correctly, it kinda looks like the outline is there but it doesnt have the appearance of the specific armor instead its plain white
