v0.18.0

Fixed

• Model moving belt pickups from the stacks within reach, including the shorter exposed length at underground entrances and exits. Try the nearest lane first and fall back to the other lane when it carries the same item. This corrects pickup timing and generated clocks on affected builds.

Added

• Choose Straight belt or Underground belt for each belt-fed inserter in either editor. Sidecar 0.9.1 captures supported pickup geometry and identifies bends, splitters and inline pickups it cannot classify. Imports and saved results show pickup coverage and the assumptions used for that run.

Changed

• Omitted pickup length defaults to a straight belt in the UI and engine. Underground pickups explicitly use half-tile reach.
• Use Moving or Backed up consistently for input supply, independently of pickup geometry. The config setting is overrides.backed_up_belts; older non_moving_belts settings migrate on import. Editing either supply or geometry marks previous results out of date.
