A heads-up overlay of your personal (character) roboport's construction range -- the zone your bots can reach to build, repair and deconstruct. Toggle it with a hotkey (ALT + Z -- Z for Zone) instead of the old deconstruction-planner trick. The border is colour-coded: green when active, amber when the buffer is too low to deploy bots, orange when out of power, and red when no personal roboport is equipped. Only your character's roboport is shown, never stationary ones.
Small changes concerning balance, gameplay, or graphics.
