Textures/materials misbehaviour, and lighting general issues

[TapeKiller]

There are some inconsistencies I've stumbled across in the game (beside just some missing textures)

 

I made an album on imgur, since it was easier than attaching image by image

Regarding map and object lighting it feels like they are treated differently, by different light sources.
The map has just its general light while objects are affected by light sources inserted in the map.
This can (often) make objects look darker than the most dark areas of the map, which just doesn't look right. 
This could also be the reason why water looks so dark in the first image, while the rest of the map looks lighter even if it's night and it's supposed to be just as dark as the water (or vice versa).
