How to clean up your game

  1. Activate the mod after the Core mod.
  2. Load your game.
  3. Find the new tab called “RuntimeGC” at the bottom of your screen.
  4. Click and do some cleaning with the GUI.
The longer you have played, the more effective this cleaning will be.
Sometimes errors occur, such as: “Tried to remove *** from RimWorld.WorldPawns, but it’s not here”. These errors are unavoidable but they are harmless, so just ignore them.

RuntimeGC is available in English and Simplified Chinese.
