Inventory disappears in the raid

When I go to the map, sometimes when I open the inventory in the raid itself, I have 1 knife and nothing else, my weapon clips are shown in the "Health" tab, and each time I open this tab, they become more and more. If this bug occurs, you have to leave the raid and re-enter the game, but the bug may appear again even after restarting the game.

If you do not understand something - forgive me, I translate this text through an online translator.

Stop using B3 and update to B5. This issue has already been fixed.

When I install B5, the game does not start, it says that you need to buy the game (I know that a legal copy of the game is required)

Then you are doing it wrong, Normal cause of this is if you have not installed it on the same drive as live/ have not allowed required privileges etc.
Solution is normally to install on the same drive, and run one online raid.

so B5 can also work on an illegal copy of the game ?
