With the new Beta interface I cannot get rid of this 'Failed installing package' message: I verified integrity of files in Steam, I removed the item from the Workshop, reinstalled it, removed again manually, etc, all without success. There error is still there even with the package uninstalled. Any suggestions?
There is a problem with that old ISI Indy track. One user had issues yet when I tried to test it, it worked fine. Probably you have an older version of a carset or the track itself. Use the mod manager or the package screen to see any mods that are tied to that track. remove the mod or carset instead of the track itself.
