I've pushed a new build which mostly solves all problems regarding troubles starting up the game. I'm going to be adding weapons and tools back soon as they need more polishing.
I had a very busy few months so I couldn't really contribute towards Sandbox Classic. The gist of it has been rewriting the bloated codebase based on HC1 that we originally had, for a more simpler and elegant solution with Walker.
TL;DR, I was occupied... sorry!
