Is there a possible somewhat easy fix for the "shiny"  

 destroyed gunpit?  
If it does not entail lengthy coad, I would think the destroyed gunpit should either:
a)  show a darkened, disturbed earth + rubble [destroyed object]
or 
b)  show burning / smoking + rubble [destroyed object]
even
c)  just remove the shine, and the "man in the moon" (second screenshot) mud face will do. (anyone else see him?) 

There are so many great graphics updates, I just feel that since, these structures have been highly intergrated into game play, they shouldn't take on this uncharacteristic shiny glass display at various angles (first screenshot).
