Yes, tested on latest successful build 467.
Full Stack: https://hastebin.com/raw/itemeneron
Rereading the issue, I can't tell if this is the same error. But this is my point of contingency 😛
@DeJayDev that hastebin link isn't working for me. Is it the same stack as above?
I saw the same issue on my server when I went to supervanish :/
Tested on latest successful build 467:

So the issue with chat packets throwing a null pointer is that mojang added a new UUID field to chat messages (presumably to mute/identify other players?) that doesn't get set by default. It seemed to be fixed in my testing with the latest dev build, but I can look into something else if that's not the case
@DeJayDev no idea what's going on with your error, but it's not related to this one. Where did you get your jar from?
@dmulloy2 I've retriggered the error (loading the plugin) and copied the error for this pastebin. It looks very different from everyone elses.
