We just released a new patch. This patch includes changes to the load/save system, changes to friendly fire, amount of resources in the Deep Cave, and a bunch of bug and crash fixes. A special thanks to community member Digger1213 for helping us testing this patch.

Full patch notes for v.0.5.1:

• Changed how friendly projectiles interact with player made machines/parts. It is now not possible to damage any player made parts with a ranged weapon (Ballista, Cannon, Railgun) if the weapon shooting is attached, or on the same machine, as those parts.
• Saving and loading is now threaded, this will drastically lower save time.
• Reworked the load game menu. it's now possible to see Save Time, Days played, Terrain type and Game mode from the load menu. It's now also possible to clone a saved game and load the newest autosaves from any game.
• When doing a manual save (from the pause menu) you can now rename the save game, this will create a new copy of the current game. Manually saving the game with the same name will still overwrite that game.
• Changed the pause menu UI button "Quit" to "Quit to main menu" directing the player to the main menu instead of exiting the game. When quitting to main menu, the player will have the option to do a manual save.
• You can now no longer load a game from the pause menu.
• Added a saving icon in the bottom right corner.
• Added a "soft crash" feature. A soft crash will occur in some rare cases if the game is about to crash, asking the player to send a crash report. It is possible to continue your game after a soft crash.
• Increased the Cannon damage (from 5 to 6).
• Increased the amount of Copper found in patches on all depth levels in the Deep Cave (example: From 25 to 58 in each patch at depth level 1).
• Increased the amount of Zinc found in patches on all depth levels in the Deep Cave (example: From 12 to 22 in each patch at depth level 1).
• Increased the amount of Iron found in patches on all depth levels in the Deep Cave (example: From 25 to 67 in each patch at depth level 1).
• Increased the amount of Lead found in patches on all depth levels in the Deep Cave (example: From 11 to 14 in each patch at depth level 1).
• Increased the amount of Manganese found in patches on all depth levels in the Deep Cave (example: From 20 to 26 in each patch at depth level 5).
• Increased the amount of Tungsten found in patches on all depth levels in the Deep Cave (example: From 5 to 6 in each patch at depth level 5).
• Increased the amount of Nickel found in patches on all depth levels in the Deep Cave (example: From 18 to 22 in each patch at depth level 8).
• Increased the drop rate of Chromite from chilled tortious (From an average of 12.5 to 17.5).

• Fixed a bug causing tiles to be generated twice if the player were moving to fast.
• Fixed a bug causing tiles out of view not to be unloaded if the player were moving to fast.
• Fixed a bug where machines/contraptions would not load into the world before all the blocks were loaded.
• Fixed a bug where tiles were not loaded fast enough when the player were moving really fast.
• Fixed a bug with text alignment causing some text to be unreadable with some resolutions.
• Fixed a bug where blueprints of big machines would not appear in the world when placed.
• Fixed a bug causing machines/parts to be duplicated if they were left in an instance and the player would leave the instance and then save/load the same game.
• Fixed a bug where the left wall in The Temple (story mode) had no collision.
• Fixed sometimes not being able to build blueprints with balloons.
