[2019] [Heavy bug] Got suddenly credited old hunt pass rewards

So one time I came back to Ramsgate after a failed hunt, I suddenly got credited a few dozen items at once, showing up on the left hand side of the screen. It turns out these were mostly, if not all, unlocks from the LAST hunt pass. I did NOT unlock these previously. I don't think it's all 50 levels, but I am not entirely sure (can't check possible rewards anymore). All acquired things persisted in future logins/restarts.

I rather not give any information about my account, i just take it as a kind reward for playing a BETA. I just thought you might want to know!
