Unfortunately, I'm also having the same issue. @Thinkofname, do you plan on updating?

I haven't played minecraft in over a year and haven't been keeping track of the changes, sorry.

Might you merge #5 if it is working then?

From a glance it looks like that PR breaks all other versions in the process.

At this point I have no issues if someone wants to fork this and maintain it themselves as I don't have the time to keep it up to date with Minecraft anymore.
