Mystery box lost when you click on item you get

Jefferx

Hi, can you check this on your side. I opened the mystery box and i clicked on the item i got. Then i click on the toon that need this item. At this moment there is a display bug that you can see mystery box in background but you see also the toon you click on it. When i close these windows. I were not able to accept the mystery box anymore, all disapear. I had 15 of that item and i still have 15. I should have 17. I can't cobfirm if i lost the other part of the box but probably. It doesn't mather what i lost, but i think a fix is needed.
Thanks
