    • This bug affects all worlds and all minecraft versions since 1.8.1 Beta (Not the newer 1.8 but the old 1.8)
    • Unconfirmed

      This bug is about the first created maps (Map item not the “world map”) being overwritten after more than 32767 maps have been created in a world (Caused by the 16bit signed integer limit which stores the ID of the map). When this happens old maps and the newer created get ID 0 and become completely empty with sometimes a small compression artefacts. This affects all minecraft version since the map item was first introduced in the 1.8.1 Beta.
