Fixed missing antlion guard step sounds Make RemoveDecalsAt distance a float Added description to sv_sticktoground Use squared distances for RemoveDecalsAt internals Disallow Spawn() on world entity Add a confirmation dialog when trying to load a save that would changelevel Change implementation of VMatrix.InvertTR to avoid it crushing itself It's probably a bit slower now, but returns actually correct values VMatrix:GetAngles uses a normalized matrix internally so scale doesn't affect results as much Added ai.GetNodeCount Properly fix the particle related crash, and fix regression
