Steps to reproduce:
On Windows, create a world with an add-on that includes a custom block using number-type arrays in its block states (Attachment 1).
Start the world and open it to LAN or invite friends.
Try joining from an Android device.
Expected results:
Android players should be able to join the world and play normally.
Observed results:
The Android player is disconnected with the error code “Boat” (Attachment 2).
If the add-on contains custom blocks using other array types, the Android player can join normally (Attachment 3–6).
