Potion Glitch For 15w31a,b

On Minecraft Snapshots 15w31a And Up, Custom Potions and Splash potions Produced By Map Makers Now Have No Texture, Just Showing A Pink And Black Block Texture. Custom Splash Potions Now Acts as Normal Potions After Update. Please update Textures so I Won't need to Redo A Lot of My Maps! (Potion Effects STILL WORK But Texture Are Missing.)
