I don't know what you are encountering Gray Lensman, but "details" would help us help you... You mention "A temporary deletion of the /Users/Name/Documents/SH4 and rebuild eliminates the bug but..." You cannot "temporarily" delete the folder and then restore it after activating the mod. It has to be permanently eliminated, if you haven't done that. Otherwise, any incompatibilities are re-introduced to the modded game.
I have both TMO and FotRSU installed (as well as a half-dozen other mods) in my Games folder by use of MultiSH4. That way, I can noodle in which ever version of the game I want to... One of the big things with FotRSU is a "proper" LAA (or similar) activation on an SH4.exe file that is NOT write-protected... Let us know please:
1. Where you have your SH4 installed?
2. Your OS, whether 32-bit or 64-bit and how much RAM you have?
3. Did you use a "fresh" SH4 install, whether a re-install or from an archive?
4. Which version of the mod are you attempting to use?
5. What are the circumstances surrounding your issues?
Let us know what you can either way though, so that we can look for potential problems in the mod. Thanks
