"Treasure" maps just empty maps

-Chests in shipwrecks that would normally generate with buried treasure maps instead generate with empty maps.

-The lag time expected of chests generating treasure maps still occurs; however, when chest contents load, there is no treasure map.

-Tested with two shipwrecks on seed 1156004263328896433, Amplified world type. Coordinates of chests are 39, 46, 622 and -413, 51, 849.

-Shipwrecks were checked in two worlds with the same seed, once in Survival and once in Creative. Empty maps appeared instead of treasure maps all four times.
