Resolution: Works As Intended
Affects Version/s: Minecraft 1.12.2
Fix Version/s: None
Nether stars (dropped by withers) currently despawn after 10 minutes.
I would have expected them to despawn after 5 minutes, or else never despawn at all / be invulnerable.
This may be works as intended, but if so the MCP names are incorrect.
1. Kill a wither.
2. watch the nether star drop.
3. drop a stone block nearby.
4. note the stone block despawning.
5. Note that 5 minutes after the stone block despawns, the nether star despawns.
