RC2 crashing
 

When you try to upload more then around 100 (dont know the exact number), your RC will get disconnected from the server. This is a big issue if you need to upload for example an overworld like I was trying to do with 4000 levels. I was using RC 2.05 on a Windows XP system, I dont know if theres was an error with RC 2.04.

I tried using the old RC 1 to upload them, and then it worked fine. Thanks to Skyld for suggesting to try a older version, although I dont think he had RC 1 in mind..

Well there, Ive brought it to your attention Stefan, work complete.

It might have to do with the filesize limit.
