I bought two add-ons today and they are visible but I can't download them, which is annoying me, I only write in-game content and downloadable content, when I download the whole thing with all the add-ons, only these two don't download
TomiLoczek Those look like the early-order bonus content for Royalty & Legacy and Enchanted by Nature, not the packs themselves, although I'm not completely sure because of the language. But this is exactly how the bonus content works: it shows up as "in-game content" rather than a pack to download.
The expansions themselves should show up as their actual names, not the names you're seeing. If you believe you bought the full packs but haven't received them, contact the retailer to ask for codes for the EPs rather than the bonus content.
