So the title problem prevents me from uploading anything to the workshop. More precisely, it is about the world I want to upload. The message "Uploading a file to the steam workshop failed" appears. So I tried a few more times and nothing. I decided to check the content of my workshop and to my surprise there are 5 files without a miniattarius, without a title, date and with a file size of 0.00000000MB
by entering a given file, information is displayed: "Current visibility: Hidden. This item will be visible to you, administrators, and anyone marked as a creator."
