Spigot uses a no longer valid ClientboundContainerSetSlotPacket with the slot -1, which would update the carried stack in versions <=1.21.1 but now leads to an IOOB. 1.21.2 instead introduced the ClientboundSetCursorItemPacket, which this patch uses instead.

Subject: [PATCH] Correct update cursor
|
|
|
|
Spigot uses a no longer valid ClientboundContainerSetSlotPacket with the
|
|
slot -1, which would update the carried stack in versions <=1.21.1 but
|
|
now leads to an IOOB.
|
|
1.21.2 instead introduced the ClientboundSetCursorItemPacket, which this
|
|
patch uses instead.
