Whenever I run ut2004 with my mod (using the old style of specifying inis on the command line with the proper paths), I get a "Log: ERROR: Could not open _.u for reading!" for my code package. When in the game menus, it fails to load the classes for everything from my mod and outputs tons of errors, but if I go to host a game or instant action or the like, it loads up the mod fine and gives the custom weapons, lists the maps in the custom directories, etc.

Any idea what would cause this? It is as if it only sees the package once the actually game starts.
