I was downloading the 80225 version of 7.50 DLC Cradle of Humanity and it stalled out. I cancelled the download and tried to download it again but the DLC had been removed from my library. What is going on?

Same here, windows and linux download seems to be missing

I'm facing the same issue.

I figured out how to download the file, though I'm not sure how reliable this is for everyone. I was able to get the installer file this way but I'm also worried that GOG took the file down for a reason. If the website just isn't showing the file by accident that would be one thing but if they took it down because of a flaw in the file that would be something else and I'd hope they'd tell us.

Anyway, here is the link I wrote that worked in downloading the file.

gog.com/downloads/x4_cradle_of_humanity/en3installer0

Timelines is also missing.

I'm grad I still have the 80150 files here.

DLCs seems to be again visible for downloading.
