No, it's script related. All textures work even though some are weird looking (example, drawbridge in Airport district), I plan to correct that in the next version. NPCs don't freeze in my game even with version 4.1 of this mod installed. That could be something to do with NPC scripting. What does Chunk4 has to do with this mod? Chunk4 isn't included in Masamaru's Saints Row 2 High Quality Texture Pack mod either, so explain yourself.
