Help with Purchased Add Ons

Hey guys, Apologies if this seems a really daft question but I've been banging my head against a brick wall for a while trying to work this out. I purchased Tales from the Yawning Portal a while ago and whilst it shows up in my Marketplace Purchases I can't seem to add it to my games. I've scoured Game Settings for it, yet I can't seem to see it even after using the "Find" option in Chrome. Am I looking in the wrong place? What am I doing wrong?

Have you looked at the  Game Addon wiki page? You have to go into your game settings (not located in the game) to find Game Addon menu button.

I have indeed. Followed it exactly but "Game Addons" just isn't in my Game Settings, which is why I'm so baffled.

I found out some updated info. If you scroll down your details page for your game, you should see the game addon button below the game description. The wiki page is temporarily out of date but will be updated to reflect the new information.

Oh good god. Thank you so much Pat! That's extremely embarassing on my part. Thank you for taking the time to point it out to me. It's much appreciated.

You think it is embarrassing? How about me going to a dev and asking where it got moved to? That is a facepalm moment for me. :D Glad to help you and hope you enjoy it. One word of warning, Addons will drop lots of files into your game so be prepared for the deluge.
