New GMod Update Issues

Ever since the new gmod update of a couple days ago, my server keeps re-downloading these files every time the person connects:

And now the Q > Tools > Render > Materials menu doesn’t show anything.

Would anybody be so kind as to help me? Thank you.

.ain file isn’t much to worry about. The other 2 are. Now, I know that the duplicator in Gmod got updated recently. My 2c are this. The server is yet to run a steam update, causing old versions to be downloaded, OR, The server has a Fast DL option that either isn’t set up correctly or is mistakenly enabled.
Remember, YOU NEED TO UPLOAD THE CACHE/DUA FOLDER FROM THE SERVER TO THE FAST DL PLACE.
Otherwise It will not work/loop files over and over again.

Aha, I had to update the dua folder in FTP.

Thanks man.
