Tag: previewbug (Owner: jopojelly#0000) Looks like you are running into a bug on the preview version of tModLoader (preview-v2023.X). You likely didn't intend to be on the beta/development version of tModLoader. Many mods won't work on preview. To switch to normal stable 1.4.4 tModLoader, close the game, right click on tModLoader in Steam, click properties, then betas, then select None in the dropdown. Steam will now download the files.
