Isnt TerrariaServer.exe just the terraria source with a few variables modified? Thats what Yoraiz0r told me anyway. Also, in this source Chest.Unlock(int x, int y) does not work, but that method can be copied from JustDecompile and then chests unlock just fine. Also, waterfalls dont animate, which can be fixed by copying WaterfallManager.cs from DotPeek (JustDecompile doesent decompile it properly)
