- Because thruster nodes now store independent state, they can no longer be shared between models.
- This highlights a major inefficiency of the model system, where there is no way to differentiate between shared and instance data at the level of an individual node.

- Previously, if the player did not pay attention to the 'Installed' text they could sell the currently equipped item and buy the same item, operating at a net loss.
- This does not gray out the item in the list, but only the 'buy' button.
- Display a tooltip to the player indicating the item is already installed when hovering the equipment card.

- Introduce EquipType:CanBeSold(), checked in the ship equipment menu.
- Passenger cabins are currently the only users of the method, but supports the generic field EquipType.inhibit_removal to allow modules to install equipment that the player cannot remove.

- Bindings were being read from the wrong section due to a poorly-designed API with ambiguous optional parameters.
- Centralize all config-related operations in Input::Manager.

-  Add debug-mode assert to validate geom index when looking up static geoms.

- Not exactly the same backtrace as pioneerspacesim#6118, but similar expression. Should hopefully fix the problem.
