Added a crash report for when an item with a section sign crashes the game, it results in a NullPointerException as well but the description that goes along with it is different, that being "Exception ticking world".
Confirmed for 18w11a.
The game crash also occurs whenever the section sign (§) is used inside of a name or lore of an item (using the symbol in functions allows for color codes to work).
The same problem occurs with the X and Z direction past the world border. Teleporting entities past the 32-bit limit (plus or minus a couple hundred blocks) will crash the game and can potentially crash the game indefinitely. My suspected theory is that when changing syntax to many commands in 1.13, the +-30 million x and z limit as well as the 4096 y limit for teleportation wasn't implemented (at least not yet).
It happens constantly and consistently. This is no coincidence; if it were it would be an astronomically low coincidence.
Confirmed for latest snapshots 17w17a and 17w17b.
Confirmed for 1.11.2 and snapshots.
Ah, ok. Never knew, thanks for letting me know.
Confirmed for 17w17a and 17w17b.
Confirmed for 1.11
Confirmed for 1.10
Confirmed for 1.9.2 and new video in description.
This is not a modded server, all I use is an OptiFine client which does not affect the server. We use the 1.9 Minecraft server jar. If you want, I can make a new video with the pure 1.9 client.
Confirmed for Minecraft 1.9
I'm sorry, it was recorded by one of my server staff members. But they are selecting the correct number, this happens quite frequently for them.
Confirmed for 1.9 release
Nonetheless, the command still cannot differentiate a pickaxe with only efficiency 1 and a pick with efficiency 1 and another enchantment, it will see the 2nd pick the same as the first and still emit the command, even though it only tests for efficiency 1.
@FVbico https://bugs.mojang.com/browse/MC-123839 was reported and resolved as a duplicate of https://bugs.mojang.com/browse/MC-123782 , and this was marked as relating to this bug and fixed. One of those two bugs should likely be reopened as they were not completely solved.
