Hello, thank you for sharing your information.
If the stitched images are already incorrect, then the error occurs when assembling the many small downloaded satellite image tiles by "Stitch Image Tiles" process.
Geoconvert then converts the incorrect base image for Aerofly FS4 1:1 (raw images for verification and all ttc files), and the Shrink TMC grid square factor has no effect.
Unfortunately, this type of error is completely unknown.
So that I can carry out further checking and see whether the error can be reproduced on my end, you would need to share your entire working directory with me via direct contact (Google Drive, WeTransfer or what ever).
