I checked the folder where mods are downloaded to and I already had a bunch in there that weren't appearing on the mods I had installed in game so I deleted those files as I thought that was the problem (trying to install cheat sheet when cheat sheet is already installed etc.) but no luck. So I recently changed over to the steam version of tModloader and checked the mods I had downloaded on the browser and it said I had none so I went to download one, I tried to download Cheat sheet to give an example and it wouldn't download it would got o the progress bar and then go back to the browser or would stay stuck on the progress bar, this isn't limited to just Cheat sheet, I tried multiple mods and none will download.
