Hi Darxxus
Many thanks for looking. I don’t have the design dlc showing up in either place, just the doors dlc. Using GOG galaxy it claims the design dlc is installed and fully up to date (1.81d). Disabling GOG Galaxy and installing from .exes gives me the same result as well. Looking in the folders I can’t see anything that looks like the design dlc. In the content folder (…\Production Line\content) I only have a single folder called “dlc1” and the associated .txt file.
I’ll keep trying things and see if I can get anywhere. Thanks again for looking.
