In the brewing stand, any potion which I attempt to create becomes a water bottle. The texture is a purple and black checker. This happens for every potion. Plugins which give players potions also fail to work. I am assuming that potion ids have changed and spigot has not changed with them causing potions to fail to be created and textures to fail to load. When I have a potions wit the id 373:8201 it is a purple square and it is titled water bottle. (This used to be a strength I potion)

If I go to creative and grab a strength 1 potion the id is: 373:0. In fact all potions are 373. It is as if they no longer use durability and have resorted to item meta for potions. Please fix this as soon as possible.
