When I click the correct seashell I get an experiment 404 error page that says "Oh no! This is an invalid game." I went back and tried a couple times in a row to get the exact same result. I don't want to click the wrong seashell because of my tiny win streak but if I need to try that For Science I will. I'm on OSX using Chrome with no applicable extensions, and I've done a lot of questing and wardrobe work today without any trouble at all. :)

have you tried refreshing the page

I had no problems with it earlier

I did refresh it then but I tried it again now and it seems to be working fine ~~ whatever it was must have sorted itself out. Thanks!
