Arrows in movement despawn after one minute

[XavierBit]

Expected behavior

Arrows in motion should not despawn.

Observed/Actual behavior

Arrows, pushed by pistons (for chunkloaders etc.), despawn after one minute, even when chunks are player loaded. This interferes with different farms and contraptions.

Steps/models to reproduce

Connect a skulk sensor to a piston with a repeater and shoot an arrow in the piston. The piston will push the arrow up repeatedly and, as it is in motion, it should not despawn.

Plugin and Datapack List

Tested on a vanilla server setup with no other plugins besides Spark.

Paper version

Paper version 1.21.11-69-main@94d0c97 (2025-12-30T20:33:30Z)
(Implementing API version 1.21.11-R0.1-SNAPSHOT)

Other

Setting 'max-arrow-despawn-invulnerability' should be on 'disabled' to be on parity with Minecraft 1.21.11.

This was an intentional change, using the setting that you've already mentioned is the way to prevent it. This setting is also documented on the vanilla-like experience page of the docs.
