clock type mismatch in incremental compiles

If I were to take a guess, it is locked to CLKCTRL_R32 but the internal promotion is making it a periphery clock. I don't believe assigning a clock to a specific location such as CLKCTRL_R32 guarantess it will be promoted to a regional. (It seems silly, but very seldom do users lock down to specific Regional locaitions). Now, when I've used partitions set to post-fit, this has always been resolved for me through the partition, so not sure why it wouldn't occur here, unless perhaps the source transceiver is outside of the partition? Just a guess. Maybe take that name into the Assignment Editor and make a Global assignment of type Regional. Just a guess though.
