Hard to know what’s wrong without seeing your code, but my guess is you are passing a world position to world_to_map.
I regret to inform you this method doesn’t expect a true “world-space” position. Instead it expects a position local to the tilemap. If the tilemap is moved, scaled or rotated, you have to first convert your position to local space, and only then, you can call world_to_map:

var tile_pos = tilemap.world_to_map(tilemap.to_local(world_position))
