Updated for .11.x
Bad news everybody!
Incompatible with .11.5
Took me about an hour of troubleshooting to pinpoint the problem of moving to .11.3. (wrong format for platform_picture in entity.lua)
No idea how to fix the new problem in .11.5. (attempting to "generate chunk in unreasonable position")
It's unlikely to be MP compatible, but I don't see why it couldn't become as such with some more work.
Now to downgrade myself back to .11.3. The things I do for you guys.
