[ARCHIVED] [DU] Diploma displays wrong university

I finally had a Sim finish a second degree. Justin Dyer's first degree is a Distinguished Degree in Art History with Honors from University of Britechester. His second degree is a Distinguished Degree in Biology with Honors from Foxbury Institute. His Biology diploma is from the wrong university.

Both diplomas are titled Magna University of Britechester Diploma.

The details for both diplomas say they are from the University of Britechester. They do have the correct majors and they both say With Honors.

The information on the Simology panel correctly shows that the Art History degree is from University of Britechester and the Biology degree is from Foxbury Institute.

Justin attended both graduation ceremonies. The ceremonies took place at the correct locations, the first one at Britechester and the second at Foxbury.

Justin lives at Honeydew Fields in the Gibbs Hill neighborhood of Britechester.
