I didn't find anybody reporting this so i don't know if its just a display bug.
e.g.
After i confirm a bunch of single auroras and then delete one of them it displays that i bought the remaining.
I din't buy them or lost credits. After i reopen the shop its still the same.
After relog it shows none.
When i confirm 2 groups and then delete both of them it still shows the 2 groups in the lower section.
The total cost is of the 2 groups. After i press buy they both disappear and i didn't buy anything.
