[War3zuk Alpha 19 All In One]

@War3zuk

I'm using the full launcher version of the mod, no other mods except an extra car mod

but buildings are breaking down no matter what map

How can I tell, there are traders in various parts of the buildings, 
gray marble-type blocks are formed on the doors 
or at the bottom of the buildings,I can enter them 
I don't understand this in some way. How can I solve it please help?
