LSB Gone after failed payment

Let me start with saying it's unbelievable that every time you release a LSB the same issues occur ever since you guys started the LSB only with gifts in jan/feb (maybe fix the code behind it?).

This time I tried to buy LSB HOTH on PC Client. sometimes a white window pops up preventing you from continueing with your purchase. I restart the game (that fixes the white window bug) and then the LSB is gone. Every single LSB this year had this issue; if you don't succesfully purchase it (or check prising and not buy it) it will no longer be available*.
