I have reached level 96 in the current battle pass but can not claim my free reward at level 72. When I clicked it, it just said that I had uncollected the previous reward, which is impossible (Obviously, I have collected the reward at level 68). If I click the ‘Go to unclaimed reward’ button, it just jumps to Level 96, my current battle pass level.
I tried to sign out and re-enter the game, and this did not help.
I have joined the battle pass event from the first one, and such a thing never happens.
Restart the game and/or play a match, that usually fixes it for me. :)
