What you were expecting to happen, and what actually happened: I bought the guild wars pass. Was able to get in today and claim my rewards for the last day but still was not able to buy (for 20 gems) the last 10 King Mikhail shiny tokens. System wouldn’t let me do it after my Sunday fights either.

Steps to make it happen again
REPLACE THIS TEXT WITH YOUR ISSUE. e.g. Sometimes there are certain steps that can lead to a problem that may not be obvious! Example: I lose once in the Arena, I then exit to the world map, select broken Spire on the Map and enter Arena. broken spire’s quest lost instead.
