Unused Pin Behavior

Thanks to both FvM and saranshmeh for the helpful replies. I knew immediately about the Device & Pin Options Button, but unfortuneately missed the unused pins tab. I was able to make that change and recompile without incident. I had another problem related to my debugging of a processor interface to an EPCS4 that works in parallel with the FPGA. I'll update that thread with what happened and what I had to do in addition to get theings back where thry were.
