All arrow types lose their name/NBT data when shot and picked up

same for boats and minecarts

I think this works as intended. As annoying as it is, entities are not currently capable of retaining information from their item state.

Well I imagine it could work just like spawn eggs do, actually it would be pretty cool if boats displayed their names like mobs do.

Minecarts have been fixed, but arrows from a dispenser, etc. haven't.

Confirmed for 08a

Confirmed 14w10a,b,c
Arrows shot from bows, snowballs thrown at friends...

Command blocks are affected as well. They retain their NBT data but their name gets replace by [@]

At least cakes have been fixed in 1.8.

This happens for banners as well. It happens in 1.8.1. Maybe it's intended. But, please, make sure the names (given by using the anvil) are saved even after you have placed the banner in the world.

also happens to saddles on pigs(annoying when you get the achievement via a named saddle)

the tipped arrows work for this in 15w31a, yet normal arrows don't

Confirmed for

• 15w44b as the entity TippedArrow does not longer exist (arrows have now only the tag Potion) they are also affected

So basically all arrows are now affected?

Yes

Confirmed for 1.10.1.

Confirmed for 1.12-pre5

I named some arrows Bullet and picked them up. They were named "Arrow." That was in a snap shot for 1.8.

Currently only version 1.12 is supported. 1.8 snapshots are almost 3 years old, you should really update! What do you even use to start these? They are not in the regular launcher.

Can confirm for MC 1.12.1.

@unknown It's usually not very useful to confirm something for every past snapshot, only for the current one and the latest release. If you want, you can check which version introduced a bug, but I don't know if Mojang looks at that.
