Texture and toolbar icons missing and other problems

Hello, I have post these problems on feedback block but then I find that may be a wrong place, so I post them here again... all of them come up after the Warfare2 update.

1.The icons on toolbar are always missing, some icons may come up after pressing the num keys for a while, but if I switch to other toolbar page the icons are missing again. And the textrues, I can not see any textrues on blocks now... the sunshine will disappear for miniutes when I just load a savefile.

I have upload my newest game log files on the Pastebin as Dan2D3D suggested on steam community, here is the link below:

The problem actually looks like the screenshot below:

And my graphic card is Intel(R) HD Graphics 4600, it is an integrated graphic card on CPU but works well before Warfare2 update, at least the texture and skin of things are shown in the right way.

2.The collision box size seems to be bigger after the warfare2 update, which looks like the old version about 1 year ago. It makes many vehicles built during last year espacially with subgrids run into trouble now, so is there any plan to resume the collision box size?

3.Where can I find APIs about target locking and APIs of searchlight? Is there a plan to add function for the custom subgrid turret returning to the reset position just like other turret blocks?

Thanks!
