Because this exploit has been widely known for years and has not been fixed by Mojang, we decided that it was worth allowing people to toggle it on/off due to how easy it is to make it configurable. It should be noted that this decision does not promise all future exploits will be configurable.

Subject: [PATCH] Fix setPatternColor on tropical fish bucket meta
|
|
|
|
Prior to this commit, the tropical fish bucket meta would set the body
|
|
color to the previous metas pattern colour when updating the pattern
|
|
colour.
|
|
|
|
This commit hence simply fixes this by using the proper body colour
|
|
value when updating the pattern color.
