Additional context

The only i know is that it does not happen in calculate_aim_cap() as i initially thought

From a quick glance, the issue is the Target_attributes struct that's passed to confidence_estimate. While it has a visible member, for one that's not used in the calculations, and on top of that an empty tile has different target attributes than an enemy on an invisible tile.
