Need Bug-Free Master Anim System

I’m building a Unity-based open-world project similar in scope to GTA and I want to slot in the Master Anim System as the backbone for all character movement and interaction. I don’t need a custom rewrite—just a clean, fully functional copy of the official template.

What I’m after is the latest or otherwise proven bug-free version, packaged for Unity, ready to drop into my project without broken links, missing scripts, or licensing headaches. If you already own a stable release, please share it with me along with any setup notes you found essential.

Deliverables
• Master Anim System Unity package (bug-free)
• Any accompanying documentation or demo scene to confirm smooth import and play
• Quick installation steps or tips you’ve learned while using it

I’ll validate the handoff by importing the package into a fresh Unity project and running basic locomotion, interaction, and transition tests. If everything compiles cleanly and the animations blend as expected, we’re good to go.
