With great patch, comes great bug they say.
The Division got a new major patch recently and with this patch, some players had some difficult time. After the patch, some players noticed that their High-End backpacks disappeared from their inventory. Worse, some says they have been locked out of the game. Some of the players stated that they have been locked out for 5 days.
Ubisoft said that they are investigating the bug and trying to fix it:
We are aware that some of you are experiencing an issue where you are locked out of your account. This is usually caused by having crafted a High-End backpack. We are looking to resolve this, it’s one of our main priorities at the moment.
