Unstable Version 0.5.19.3

Bug Fixes

 * Fixed exploit by grabbing a block just before it's sold, resulting in the block being duplicated (and shrunk). Also prevents any block being passed to another holder while the player is holding it.
 * Fixed bug with enemies spawning under the terrain.
 * Fixed crash bug caused by invader events not being unhooked.

Known Issues

 * Depth of Field has been temporarily disabled due to a Unity issue with DirectX 10 graphics cards.
 * The Delivery Cannon shouldn’t open up when attached to a moving Tech.
 * The Delivery Cannon incorrectly causes damage to itself when it delivers things.
 * The Fabricators no longer display their list of known recipes.
 * Silo side mission: Woodstock stays marked as an enemy even though player has defeated the harvesters.
