Part of maps made with line and shapes tools are not visible on maps made prior to 2.0 update

Ratzing

As the title states, when I load my maps, the walls created via line/shape tool are not visible, besides the caps on shapes. No way of viewing it at all. Masks of terrain tool also appear to be invisible.
