• start ArmA3
• open the Livonia map in the editor
• place a soldier unit
• start the game
• open the in-game map
• zoom in to a position showing topographic height information (e.g. Swarog military station is at a height of 522 meter above sea level according to the numbers written on the map, whereas the height information shown under the mouse cursor only reads "354m" at the same position). That is, either the height info is 522m or 354m but not both at the same time. The deviation can be observed for any other position.

This bug makes it difficult to properly assess the topography e.g. at an insertion point thus providing plenty of space to choose a wrong approach / tactic and to fail the mission.
