Ceramics research can be researched but not documented, thus bills and production do not populate
Error: "Cannot document... assigned project not allowed here"
Error on both study desk and network terminal.
Debug Finish all research does allow pawns to study and complete bills but not document
not sure if this helps I don't see an error in the log
