I have the same problem on my account, it is very sad. I would like so much but it’s impossible... :’(
I thought I was the only one, but I know there were many others who were more vocal about it when it first became bugged after season 4
I basically started playing in Season 4. It bugs me that after thousands of hours of work it's there in my collections grayed out... alone. It disturbs my mental health.
Still isn’t fixed nor does it appear to be a concern for these people who keep wanting more money for more content. It’s a friggin shader. Shouldn’t be this big an issue since it’s a KNOWN FRIGGIN ISSUE. That’s like saying, “yeah, we know but WE DONT CARE BECAUSE IT WONT GET ANYMORE MONEY OUT OF IT SO SHUT UP
