Cook and upload process

Has the process for cooking and uploading changed at all? The last time I uploaded a mod was awhile back, and I can’t seem to figure out why my new mod isn’t working. I’m working off of this video. My mod shows up on the workshop and all the content is there after download, it just doesn’t work when I load into the game. As far as I can tell everything is working fine in the test map, which has made me wonder if the process for cooking and uploading has changed, or if I missed doing something that is now preventing the mod from working.
