It has two built-in dds files needed to modify Spring Bat and Mobile Harpoon Gun material, which uses 32 MB.
No new items, equipment, characters, or buildings were added.
If you're interested, check with the FCS.

I like the fixes and changes I'm reading, but...
Can someone please explain why this mod is almost 34 MB in size, despite how it seems to do nothing outside of fixes and changes to another mod?

For a mod this size, I must assume that it either adds a whole lot of textures or it adds a 3D mesh for a new item, equipment, creature or building.

Does this add anything new? Or does it only change and fix the things mentioned in the description? Perhaps it also replaces a mesh in the original mod with an updated/fixed mesh?

you did good job
