I've encountered a show stopper bug in FB 4.7, I get this everytime I try to build:
Errors occurred during the build.
Errors running builder 'Compiler' on project 'Bardbarian'.
It seems to be related to copying files into bin-debug. If I un-check 'Copy Non-Embedded Files to output folder', then the build works, but I must manually copy my dynbamically loaded files into bin-debug.
