Hello! 
  
I've found something that I feel is rather odd; but I'm not sure if it's a Forge issue or a Java issue (or some completely random issue that I'm currently blind to). 
Anyways, here's the log: 
  
  
  
  
I've done a couple little tests, finding that it didn't matter how I started forge, (via external jar or inputting into the server.jar), and then I noticed the 'FileNotFoundException' pointing to a 'file' that was: 
  
C:\Users\williamb\Desktop\Server_test\Server\Other_Servers 
  
...which is clearly not a file; rather it was a directory. 
  
Poking around, it seemed to be looking for the library files, which are in THIS directory: 
  
C:\Users\williamb\Desktop\Server_test\Server\Other_Servers!\NinjaLand2\lib 
  
So, I did a test by simply moving the NinjaLand2 folder (which contains the server and forge jars) to my desktop, (dropping three layers off the directory path) and there was no issue; the server ran perfectly fine. 
  
So, yeah, I fixed it, but I was wondering if this is something someone could fix for others or something...? 
  
Thanks! 
  
  
Edit: Whoa!  Wait!  I just noticed that there was a '!' missing... and, well, apparently Java doesn't like exclamation points in the file path.  Removing the exclamation point in the 'Other_Servers!' folder fixed the problem without having to move anything anywhere. 
Didn't know that; my bad!
