Core Keeper Gets Performance Booster in New Update

Core Keeper Pugstorm

The fun mining sandbox adventure game Core Keeper now runs smoother, thanks to the changes from the most recent update.

Patch 0.6.1 brings no new content, but it delivers new tweaks that will improve performance dramatically. Most of that is attributed to the adjustments in procedural generation where new terrain is now spread over multiple frames. This is felt mostly when exploring new parts of the world. Furthermore, enhancements are also made for the water spreading system, which significantly reduces load times for worlds where large sections of the Sunken Sea biome have been explored.

Some major bugs have been resolved in Patch 0.6.1 as well. For instance, a bug that was causing cattle, critters, and enemies to not be contained inside fences is fixed. Now, they will no longer escape through fences and other obstructions. Aside from that, an issue where murals would sometimes block players from digging and placing ground blocks around them has been fixed.


  • Changed how cooked food is stored in the save files. Existing save files will get converted when they are loaded for the first time. After this point, they will not be compatible with previous game versions.
  • Dedicated server will now parse human readable values as well as the corresponding integer values for setting world mode and season. So, instead of setting -season 1 or -worldmode 1, you can use -season Easter and -worldmode Hard as well.
  • Trying to load save files created using a recent game version into earlier, incompatible game versions will now result in an error message prompting the player to install the new update.
  • The maximum object ID for ingredients used in cooked food has been increased from 10,000 to 65,535. In particular, it now supports the 32,768–65,535 range that is reserved for items added by mods.
  • Enemies that spawn in groups chasing down players will no longer destroy objects in their paths while chasing down the player.

Bug Fixes

  • Fixed an issue with pets being able to damage cattle.
  • Larvas will no longer die when they walk close to a fence.
  • Caveling Skirmishers no longer quickly sidestep from side to side if they temporarily lose line of sight to their target.
  • Fixed the eyes to be glowing red again for some Caveling types where the eyes had turned black.
  • Playing certain melodies with the instruments will no longer cause the player to freeze.
  • Fixed a bug where the Sticky Toy pet talent would increase enemies movement speed instead of slowing them down. The amount slowed by the talent and Jr. Orange Slime was also slightly rebalanced.
  • Fixed an issue where entries could be incorrectly overwritten or duplicated in the previously joined servers drop-down menu.
  • Fixed a bug where pets would disappear after pausing the game while the pet was running to its owner.

Core Keeper Patch 0.6.1 is available on PC.
