bump?
Steps to reproduce:
(Server software used was PocketMine-MP, you could use any other server software and still get the same result)
1. When sending StartGamePacket, set the PlayerMovementType to 1 (or 2, doesn't matter), and ServerAuthoritativeBlockBreaking to false
2A. If you have server auth block breaking implemented, go into game and view what packets are sent - no InventoryTransaction packets are sent (they should be, considering server authorative block breaking is disabled)
or
2B (shown in video). Enjoy the unread bytes mess when breaking blocks

I would also like to note that this issue did not occur on the previous version of BDS for 1.21.80.
