The costumization > store tab doesn't show anything. Nothing on Bundles, Equipment, International etc. Show filters and Cart does nothing as well. The other tabs, backpack, loadout and workshop work fine. Not sure how to reproduce this, just happened from one day to another...
Edit: the cart button does work, brings me to an empty shopping cart, the continue shopping returns to the empty shopping "view". Refreshing the page doesn't work.
Edit2: The Rubik patch fixed it!
