From what I can see of your code you are making multiple Lua states.  
When you "require" something it is like a '#include <file>' in C, you  
get a copy of the code, not a shared state. Thus, the variables in  
Utilities.lua are independent from one state to the next. Of course,  
if you "require" something twice in a single Lua state then its  
variables are shared, because it is being loaded into the same state.
