  <p>Files are mixed in same module. </p>
  
  <p>Many posts online from -2011 are claiming the same sort of strange issues with mixing in the same project.  I feel real uneasy approaching scala if this has remained unresolved for years with no real articles explaining why.</p>
  
  <p>I could be wrong, so I am asking the community for their experience.</p>
