I have a zombie skin on, I have the appropriate tokens, tinctures, etc, however when I try to click on the token I want to use, it does not go from "grayed out" to darker, but instead appears not to select at all. Same for any other component of crafting. This has happened to me before, but I waited several months before crafting again, and now it's happening once more. It was working for me, and then it stopped.

Any help? I tried taking my skin off, refreshing with CTRL + F5. I'm using an updated version of Firefox.

EDIT: A lot of other things don't work on the Alchemist shop page. I can't click/collect flowers. When I do, the flower just disappears. I also can't edit my events, either.
