So, I already tried everything including clearing the Server's mod cache and still, I can't download this mod through ASM, it always fails or doesn't validate (meaning that the file comes incomplete and can't update).

I tried to do a manual installation which was successful, but, as soon as I went to search for my Server at the list, my server was not there and any attempt to join through Steam Servers would give me Error in Query. The issue only solved after I removed this mod from the Load List.

I did tried the same thing with another of your mods (Shadlos Atlas Imports) and it worked smoothly, only this one can't be downloaded, or, it turns my server unstable if forcefully installed (manually).

Any ideas...?
