[Patch 0.2.2c] This patch will use an internal converser for game saved from 0.2.2 and manage to work high density of minerals and door duplication. So first load of a old saved might take longer. It is recommended after that, to re-save so the save file will be updated: If you experiment some visual glitches after this patch, it is recommended to: Toggle off Ray-Tracing from Game Settings, then reset the graphics to any quality you prefer, and enable back Ray-Tracing if you choose (ray tracing is meant for very high-end computers, not recommended by default)
