Cannot select connected rails with 'O'
Done • Priority: Low • Fix: Dimension Update Patch 1 [0.1.1] • Resolution: Won't Fix

The O keybinding does not select connected Rails when pressed, unlike how it works for Space Belts or Pipes. When a player places Rails in a line, selects one section, and presses O, the connected Rails are not selected together. This prevents quick copying or deletion of entire Rail segments. The expected behavior is that pressing O while selecting one Rail should select all connected Rails, similar to the functionality available for Space Belts and Pipes.

"select connected" does not work for Wires and Belt Catchers
Done • Priority: Highest • Fix: 4 - Early Access • Resolution: Done

The Area Selection feature does not work properly for Wires and Belt Catchers. When pressing the keybinding O or using the select connected button, the function fails to select connected Wires at all, and only works for Belt Catchers but not other structures. The expected behavior is that the select connected feature should highlight and select all connected instances of these structures. According to discussion, this may have been partially fixed for belts but the issue persists for Wires.

Wire buildings missing (O) and (I) function to select connected and clear contents
Done • Priority: High • Fix: 1.0.0 Release • Resolution: Cannot Reproduce

The "Select Connected" (O) and "Clear Contents" (I) functions on wire structures do not work as expected. Pressing "Select Connected" fails to select connected wire, shape, or fluid elements and produces a console error (KeyNotFoundException for 'ConnectableBuildingSimulation'). The "Clear Contents" action similarly does not function. The issue was reported but could not be reproduced on a later build, where "Select Connected" worked as intended, so it was closed as could not reproduce.

[Alpha 16.2] Using "select connected" twice causes NotImplementedException
Done • Priority: Medium • Fix: 4.1 - EA Prototype • Resolution: Done

Pressing the Area Selection keybinding (O key) or using the on-screen button twice while the same connected structures are already selected causes a NotImplementedException error. This occurs when a player clicks on a Conveyor Belt, uses the select connected function to highlight the entire belt, then presses O again. The expected behavior is that no error should appear. The issue has already been fixed in a later version.
