Dear,

With the patch 1.4 we can not anymore send through concrete wall electric wire.

This was really useful to hidden these cables.

The sole survivor is able to mod up sophisticated weapon and armor but he can not to do a little hole into a concrete wall to send through electric wire ?

Please, fix it.

Note: with this patch my game crash really often while before that came one or two time. ( playing on ps4 )

You can still do this https://youtu.be/j3qFbB7rYLk

What I think you'll find (though I haven't confirmed it myself) is that you can't go through the floorboards. there's a lot of things you can not do with concrete blocks after 1.4, but you can still do the above and a select few other things.
