HAND doesn't work in 1.8.8

When using /FakeMob shop addItem <Item 1>;[Item 2];, HAND doesn't work.
This is printed in chat: "Invalid result: Unknown item type"

No error in console log besides the chat message... and this pastebin (which might be irrelevant to this issue): http://pastebin.com/NZQMYZtf
