When i take a look on my map, I don´t see any arrow or something where i am... then i turned around and watched in another direction, and then many different types of arrows and signs came up on the map where i am...
But in singleplayer and on vannilla server every map i make works, so i don´t think it´s the texturepack....
yeah verified I thought mine was acting wierd as well no plugins no tex packs (yet) but the markers was all kinds of going crazy.
