GAME INFORMATION

OPERATING SYSTEM: Windows 11

ISSUE EXPERIENCED
Some times when I create a random map in the scenario Editor, water appears over part of the land. This also occurs when I create a black map of medium and try to add land. The visual bug disappears when I save and load the map.

:arrow_forward: FREQUENCY OF ISSUE

It occurs sometimes with randomly generated maps, most often with dirt and sand based island maps.
It occurs every time I generate a blank medium water map and try to place land.

REPRODUCTION STEPS
Generate random island maps in the scenario editor at least ten times and it should occur.
or
Generate a blank medium water map then add land.

EXPECTED RESULT
Water textures and effects should not show over land textures.
