Go to your Don't Starve Together folder, open the cached_mods folder

If you have tried to update the mod it will have an extra folder for as many times as it attempted to download (563235790_76, for example)

Open folder, open download.bin with WinRAR or 7-Zip (file must be 9.91 MB or 10,152 KB)

Copy everything in download.bin, paste into a new folder somewhere

Go to the main DST directory and go into mods

Create a new folder called workshop-563235790

Paste all contents of folder into workshop-563235790
