The bug
Trying to zoom out a map (filled_map
) multiple times without placing the map in the inventory but directly in the crafting grid causes the result map (without taking it) to show "Unknown Map" as tooltip.
This affects the cartography table as well.
How to reproduce
Right-click a map (
map
)Place the ingredients for zooming out the map in the crafting table (map in the middle with 8 paper items around)
Take the map and directly put it in the crafting grid again
Place the ingredients for zooming out the map again
Hover over the result item
