take care I accidentally opened a royal wedding invite before closing one (it was finished just hadn't clicked the final complete). The second one disappeared never to return. 40k xp down the drain. BB are now aware, confirm that it happened, and have informed the developers in the hope that they will be able to do something to prevent a second one being 'opened' whilst one is running. Sadly nothing can be don about the missing 40k for some reason an expensive lesson
