Reviewed and corrected the part mapping without deleting required copper:

Not fully. I verified the four lands are physically distinct package contacts—not overlapping pads—so removing them would make the footprint incorrect.

I restored the valid 33-land geometry and documented the shared functions, but the four pairs are still separate symbol terminals. The claimed autorouter failure has therefore not been reproduced or confirmed fixed; it must be tested and corrected in the board project where this component is instantiated.

I’ll inspect the footprint’s baked pad geometry and overlap checks, then replace the problematic duplicate copper with a single correct set of lands while preserving the package’s electrical mappings.

Fixed the footprint:

Existing board instances may need to be updated to the latest part revision before retesting the autorouter.
