Detailed description of bug: There's a bug when buying KitPVP crate keys. It was easier for me to make an Imgur post about this, so see https://imgur.com/a/VTOn8Q7.
I hope this helps! :)
Also, it says it will give me 11 crate keys but I think it only charges me for one at checkout. However that's another bug too, because if I select 24 instead of 11, the price goes up.
This is a critical bug, as it can overcharge people! I don't want that happening!
