Problem

I tried a few examples from Dinnerbone's gist using /rellraw. They may be outdated, however it should not crash clients.

Fix

By looking at the source, i think that "using" has been changed to "with". Again, the client should drop this message (eventually log it), but should not crash.

Examples

Causes all clients to crash:

/tellraw @a {"color": "yellow","translate": "multiplayer.player.joined","using": ["Dinnerbone"]}

works:

/tellraw @a {"color": "yellow","translate": "multiplayer.player.joined","with": ["Dinnerbone"]}
