Bug description: When using the new modular aircraft structure in MSFS 2024, inheriting SimPropContainers via attachments from a parent aircraft to a child aircraft causes a positional offset. Specifically, we have a parent aircraft (SWS_Pilatus_PC12LG) and a child aircraft (SWS_Pilatus_PC12NG). The child NG inherits the exact same XML attachment file containing SimPropContainers from the LG’s package source (SWS_Pilatus_PC12LG\attachments\...\loads\SimPropContainers). While the containers render perfectly at the correct coordinates on the LG variant, they appear shifted backwards by approximately 1 meter when the NG variant is loaded. The NG is inheriting the exact same file without any code changes, yet the placement in the sim is incorrect.
Repro steps:
- Create a parent aircraft with an attachment XML that places
SimPropContainersat a specific location. - Create a child aircraft variant that inherits this exact attachment file from the parent’s directory.
- Load the child aircraft in the simulator.
- Observe that the
SimPropContainersare offset (shifted backwards) compared to their correct position on the parent aircraft, despite sharing the same coordinates in the inherited file.
