There is no notification when you buy a container, when you click directly after your first click coz you thought your click wasnt recognized you will get one free container and for the 2nd you get your -100GS.
1.I cant provide any logs or screenshoots unless you promise me to give me 100GS to reproduce it
When you have a free Conrainer left to redeem and you double clock on the button you will get you free containter & one for 100(350)GS; and the game wont promt any window that you have to pay something.
Suggestion: add to the network pacekt a variabel that says that this should be a free container so you only get one container ,so you cant accidantly purchase an container
