Hello, I'm an old returning player with only the base game to my account. I've been trying to find how much the expansions were in the store, but when I try to upgrade to one...it just doesn't do anything! it reloads the page and doesn't add anything to the shopping cart. I tried on different browsers with the same result. Is buying the expansions disabled or what? The fact that there are no price listed on the page was annoying enough, but I can't even add it to my cart to even buy it, it's kind of ridiculous. Makes me think twice about upgrading at all.
