In Spaced Out! Early access DLC probably i found a not important bug, but i want to help the development. If some building orders are given and some material is falling to there (sand, mud, polluted mud) the texture is dissapear. If it can fall over, this bug doesn't appear. This bug happen only, when the building can stop it. So all tile, bunker and airlock can stop it, so the material disappear.
Must to give a building order, under the falling material, and dag, to fall over. Build must be to a Bunker, airlock, or tile
