potion coversion/texures missing

all my potions (extended invisibility potions,extended leaping potions, extended swiftness potions, extended strength and strength ll potions) seemed to have converted to water bottles that are just giants pink and black cubes. When i got the 1st snapshot it did this and it still persists in the 2nd snapshot. I could not re-create this on my creative world or any new world generated in the snapshot versions. My glitched world was generated in mc 1.8.7 and my creative world was generated in mc 1.8.8.
