So I read about this a while back in some other posts but it had never applied to me. However, following the new patch if I want to build something and have the exact amount of materials available it won't allow me to build.

For example;


Wooden Wall

Wood 400/10

Steel 4/4


Doesn't let me press X and doesn't even show up for placement.

You can build only on those green marked areas on your screen. (if that's the problem)
