Every time I open my PDF of the City of Mist core book, which I purchased 5 years ago, it has my deadname on literally every single page. Even if I redownload now. I should just fucking pirate it.
I didn't buy it through DTRPG, just through their own store (along with the hardcover) so I can't even try to redownload it and see if it updates the watermark to a different name, it's just whatever credit card info I used for that purchase.
