No need to re-upload the game
, I found a newer build, uploaded it on mega. Here is the link of my upload,
https://mega.nz/#F!olpXhS4Y!eA69oFqHO1CaZIvD8LbHtAPosting it in the User Uploads section.
It's Garry's Mod v16.12.01 (No-Steam). Got it through a torrent file (it is not the latest 2019's build but 2016's build), will try to find the latest builds and upload if I find any.
