This 2 Screenshots are taken only a couple minutes apart from each other. While it shows for me that i would still have 2 hours to buy something. i can only click the bundle, but not the items. While i still see 2 hours left, my friends sees a -1 second counter. I noticed i can still click on the bundle, but the items themself are not clickable anymore. I have the bundle already bought, therefore I'm not sure if somebody could have still bought the bundle.

It looks like some client caching as it appears different on restart but not on instance switch.
