 Description   

When leaving and re-entering the game the player and other mobs

  • glitches trough the minecart and the block below, if just one block below the tracks
  • or sinks into the block when there are more blocks below the tracks. The minecart is invisible then.

Minecart is standing still.

Update: This applies to all ridden entities Minecarts, Boats and Pigs.

You might be talking about MC-96954. If not, just create a new ticket. We understand when obscure issues aren't found easily using the search function.

Comment by Spake Miner [ 13/Feb/16 ]

I tried searching if there's a bug report of this already with no luck, but I don't really want to report it because the chances somebody else already reported it are high. Search functions aren't really great in the Bug Tracker.

Very likely something else.

Comment by Spake Miner [ 11/Feb/16 ]

I don't know if this is the same issue, but I'm experiencing something similar in 16w05a (I know, it's not the most recent snapshot, but if somebody experiences it in later snapshots, also note); When you get far enough away, entities will seem to dismount their vehicles, even though they're actually still on them (By reloading the world you can see they're still riding the entity). Is this the same thing or something else?

@Ben Slimane Khaled Skander: Could not reproduce that "sitting Mob" issue, got instead a "sinking mob" issue, see screenshot.

I don't know if it's the same bug,
but sometimes when re-entering game, the mob stay stuck floating in sit-position in mid-air without minecart to support him

Comment by Novantis [ 17/Jan/13 ]

Yeah this has been in the game for a really, really long time We definitely need a fix.

Comment by [Mojang] Panda [ 09/Jan/13 ]

This bug should really get fixed with the minecart improvements planed for Minecraft 1.5.
It's still happening in 13w01b.

Comment by WolfieMario [ 10/Dec/12 ]

Ah, thanks. Although, I just noticed, the wording is really awkward: "Player and Mobs falls out out boat upon reload"?

Perhaps "Players and Mobs fall off vehicles and other ridden entities upon world reload, glitching through blocks"? That's more concise and less confusing, I think.

Updated summary

Comment by WolfieMario [ 10/Dec/12 ]

Can the thread title be updated to reflect that all mobs leave minecarts upon reload? This breaks redstone contraptions too; it may better get Mojang's attention if you changed the title.

Comment by WolfieMario [ 07/Nov/12 ]

It's because there's nothing to save an entity riding another entity. For example, animals in minecarts will exit upon reloading the chunk, and spider jockeys will un-jockey.

Comment by Kumasasa [ 29/Oct/12 ]

No, I think not. MC-814 fits better.
