Don't know quite why is happens, but it shouldn't.

So I think what is happening is the the logging system calls into FMLLog.log which treats the test as the format.

LogHelper.log(Level, Object)
-> FMLLog.log(MOD, level, String.valueOf(object)
->FMLLog.log(String, lvel, format, ... data)

So if there is anything in the path that can be translated by String.format as an escape sequence, then it is going to fail.

Escaped the '%' which solves the issue for now.
