Before 16w07a I could make a bunch of command block minecarts with some commands and one with kill command to clear them out.
/summon MinecartCommandBlock ~ ~ ~1
{
Command:"/say start",
Passengers:[
{id:"MinecartCommandBlock",Command:"/say 1"},
{id:"MinecartCommandBlock",Command:"/say 2"},
{id:"MinecartCommandBlock",Command:"/say last"},
{id:"MinecartCommandBlock",Command:"/kill @e[type=MinecartCommandBlock,r=0]"}
]
}
Since 16w07a they doesn't disappear. In 16w06a they worked fine. Ran once and all disappeared after running the /kill minecart. Now kill with r=0 doesn't kill anything.

I found out that even typing into chat /kill @e[r=0] doesn't kill you. It should kill all entities with same position as me including me.
This seems to be the same as MC-88533 which now effects all entities, not only marker armor stands.
I'd say collect them there

Could be, but It might be different. Before marker armor stand was a problem. Now r=0 is a problem.
But since it's the same issue (r=0 cannot find the executor) I just suggest to merge them.
+ it has a detailed description and is assigned already
/kill @e[r=0]
is still broken, so does
/execute @a ~ ~ ~ kill @e[r=0,type=!Player]
, so annoying and pls fix! (I think the r=0 is the broken, nothing seems to work with r=0)

The problem is that command is executed in middle of block instead of where the entity is executing command.
Ok, I made a new report to point the problem.
MC-97316 - Executing a command from command block minecart and via /execute is running from middle of block instead of the position of entity

Cause in 1.9 pre 3 r=0 no longer counts as r=0.25, this bug is back. r=0 can't find anything, even when entity is in the same spot where distence is counted from.
MC-95352 should (or will soon) cover that.
I've finally managed to find time to update it. Thanks for the help and patience, redstonehelper.
Possibly related to the fix of MC-95352.
