Does anyone have the NetworkManager .cs file from Unity 5.3?

Title says all. I need this because whenever I quit a match, I cannot rejoin since I get

Spoiler: The Error

ArgumentException: An element with the same key already exists in the dictionary.
System.Collections.Generic.Dictionary`2[UnityEngine.Networking.Types.NetworkID,UnityEngine.Networking.Types.NetworkAccessToken].Add (NetworkID key, UnityEngine.Networking.Types.NetworkAccessToken value)

Something about the network id already existing, and it cannot be rewritten.

I know that this is fixed in the 5.4 beta, however I am working with Unity 5.3. I would like to avoid using the beta with my main project until 5.4 is officially released. Also, if someone has a solution, that works too.

 

You can access the Unet Source on Unity's BitBucket or use ILSpy to decompile the dlls in <Unity Folder>\Editor\Data\UnityExtensions\Unity\Networking.

BitBucket will have the easier-to-read version but is only updated for non-patch releases and even then, the update schedule is super flakey (It didn't update for 4 months between 5.3.0 and 5.3.3).
ILSpy can be used on the dlls in your unity install so you don't have that issue, however, because it is decompiling a dll, it will be missing comments and certain things like constants will be replaced in the code. (When constants are built, they replace their references in code)

 

Thanks, I'll check it out.
