Issue with commands that didn't update world for all players

This ticket is invalid as it relates to a modified or 3rd party client, server, or launcher.

• Any non-standard client/server/launcher build needs to be taken up with the appropriate team, not Mojang.

• Any plugin issues need to be addressed to the creator of the plugin or resource pack.

• This site is for addressing issues related to the base unmodded Minecraft; Bukkit, Forge, Optifine, or any other modded system invalidates your ticket, unless the behavior can be reproduced in Vanilla.

• Additionally, if you have problems on large-scale modded servers, please report it to their site. It's probably not a bug in Vanilla Minecraft.

Fienxjox, can you explain me why for you this bug is invalid because of a modified or 3rd party client, server, or launcher?
We use the official minecraft 15w38b as server and client without modifications like mods or plugins.

If you would like to see your screenshots of the issue we get on my side and the other player we can send you it.

Any error on a client and/or server being used with ANY changes from pure vanilla, including a different launcher, is by default invalid as far as this bug tracker deals with. If you can reproduce using nothing but vanilla (including the launcher), please upload that (complete) crash report.

at org.multimc.onesix.OneSixLauncher.launch(OneSixLauncher.java:394) [NewLaunch.jar:?]

Ok so i will reproduce it with the launcher : you will have too the screenshots of the problem. Do we post the new informations on the same bug report (MC-88956 here) ?

Thanks again for your answer Fienxjox.

That would be fine, we can always re-open the ticket.

Any news about the issue? Is really resolved since I send you the new report yesterday?

I can say too that the issue exists when you are 2 or more on the chunks where you applied the command. When you are alone on the chunks, the command is executed successfully without errors and without update world issues.

Bug/Issue (in creative and survival mode) always present in 15w36d. Any news or confirmations about it??
