Collectible Card Game Headquarters

Hello, first time poster here.

I just downloaded HQ pics for two sets and I followed the instructions to import data to Forge. It takes almost forever for Forge to analyze the folder that contains the card pics and it seems that it doesn't work. Is this normal? Any possible way to just manually copy and paste card pics to a specific folder?

as long as they're properly named, and in the right name of folder for sets if using set pictures, you can simply drop them in the C:\Users\<USERNAME>\AppData\Local\Forge\Cache\pics\cards folder
