• Aligned museum entrance to the center (was 8 units off to the RED side).
• Reduced texture cache (from 254.35 MB to 210.56 MB).
• Moved teleport destinations further to prevent teleporting back and forth unintentionally.
• Improved cabin middle stairs lightmap shadowing.
• Opened up mall ceiling player clip.
• Fixed health packs clipping through the table.
• You can now stand behind the counters in the bar.
• Added 3D Skybox exit.
