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 MC-252817 (green map markers do not disappear).
|
|
|
|
this bug is caused by the fact that the itemframe's item is set to empty before the green marker is requested to be removed. this is fixed by getting the mapid from this method's parameter, rather than the air block now stored by the item frame.
