Turns out it was an obvious solution. Didn't realize the build system for customizations had changed in 4.0.3 :)

Hello all,

I have 4coder-super downloaded and have the power folder in the 4coder directory.
Custom_Current has been set to Custom_HandmadeHero in 4coder_custom.cpp.
When I run buildsuper.bat everything seems to run properly but when I run 4ed.exe it loads the default setup.

I must be missing something obvious but right now I'm not seeing what it is I'm supposed to do.
