Invulnerable Fireballs are invisible/being client-side rendered on hit

I summoned a Fireball with the Invulnerable tag set to 1 and encounter some very strange behaviors of the fireball.

First, the fireball is completely invisible and only seen for a slight time when first summoned. (less then a second) The fireball still explodes and deals damage
If you attack the fireball, it is rendered as flying away, but it actually still explode where it would have without a hit. When these rendered fireball fly to far away, they'll just get set to the starting position, even if the real fireball already exploded. Relogging/Reloading seems to fix them, but sometimes they'll come back and start flying in the loop again, but will not fly in the direction they previously were.
These client-side only fireballs do not explode, even if the hit a player or a wall. The fireballs may disappear a short time after hitting them.

I used this command to test:

/summon Fireball ~ ~-2 ~ {ExplosionPower:1,direction:[0.0,-0.5,0.0],Invulnerable:1}

(Flies downwards)

/summon Fireball ~ ~-2 ~ {ExplosionPower:1,direction:[0.0,0.0,0.0],Invulnerable:1}

(Does not move, hitting hit sends it flying client side only)

(Changing the ExplosionPower or direction does not change the behavior.)

I tried providing a video, but my pc and internet speed seem to not allow me to.

I Just tried it, and I experienced the Same Bug, Remove the Invulnerable tag, that fixes it.

Still a concern in 14w08a

Updated affected version and the commands to reproduce, with explanation of what the fireball does when summoned with the command

Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases. If this has been done, we can reopen the issue.

Keep in mind that the "Resolved"-Status on this ticket just means "Answered", and that we are waiting for further information on whether this issue still exists or not. We will reopen it as soon as the requested information has been delivered.

This (for me) appears to be fixed in 1.8.2 pre 1.
However, when spawning invulnerable moving fireballs, it does not move smoothly, but little by little (I don't know a better word to describe it).

Example:

/summon Fireball ~ ~-2 ~ {ExplosionPower:1,direction:[0.0,-0.2,0.0],Invulnerable:1}

Should I report it as a new bug or only modify this report?

I'm not able to reproduce it, but if you can provide exact reproduction steps, please create a new issue.

Closing this as Fixed.
