Premium marker for Spawners: could find them on the map Archived · read-only

Hi,
I tried to find 3 different Spawners on my map: https://web.archive.org/web/2020/http://www.minecraftworldmap.com/worlds/3OOkA
Unfortunately I couldn't find any of them.
I don't think that I missed them while exploring, because I also used an X-Ray Glitch.
Do you have an idea what could be the mistake?
Thanks,
cheers Snailhouse

I have found that spawner locations are not always correct, as they are about 10-50 blocks away from where the map marked them. In result, you really have to look to find them. Only once in a while the map will incorrectly place a spawner where one does not exist, but there is only a 1/20 chance of this happening. I am not sure why this happens or what causes it.
