Hi there, you're probably wondering why “Minecraft 1.4.2” has been added as an affected version to your ticket MC-271044. I did this as we like to add the first affected version to tickets. It helps Mojang to decide what priority the suspected bug should have (and whether it is a new bug or not). Your reported behavior can be reproduced as far back as Minecraft 1.0. However, since Minecraft 1.4.2 is the first version available on the issue tracker, we have added that one.
Hi! Went through the list of tickets and all of them were triggered by a Mod with a command.
