1) Problems importing node references with similar names

Have two institutions: "University of Michigan" and "University of Michigan Biological Station". Node references to "University of Michigan" work fine, node references to "University of Michigan Biological Station" fail and produce this error: "Institutional Affiliation: this post can't be referenced."

Workaround: Change the Institution name from "University of Michigan Biological Station" to "UMBS University of Michigan Biological Station" - and reflect this in my csv import - everything works fine.
