UNITY 5.0.0f4 >>> UNITY 5.0.1f1 trouble!

Hello everyone! I'm making a game for IOS devices and faced with many problems when transferring the project from version 5.0.0 to 5.0.1. It all started with that old project stopped working in the editor, referring to an error

Leaderboard not found
UnityEngine.Social:LoadScores(String, Action`1)

The fact that the code has not been platform verification, after the addition of verification problem disappeared:

if (Application.platform! = RuntimePlatform.WindowsEditor & Application.platform! = RuntimePlatform.WindowsPlayer) {
Social.localUser.Authenticate (ProcessAuthentication);
}

However annoying the fact that in version 5.0.0 this error does not occur.
After this correction, I started to do an update to their already released games in the version 5.0.1 in the editor, everything went well until I tried to build for the Ipad. Game compiles, run on iPad ... and hung on the home screen. xCode issued line:

exc_bad_access (code = 1 address = 0xffffff07)

I tried to make in Unity 5.0.1 build his old project that was successfully met in the version 5.0.0 and have placed in Appstore - the same mistake!
Please tell me, what could be wrong? Or at least how to move revised draft back to the version 5.0.0?

The game uses a unity Ads.

 

SOLVED
The problem was resolved by switch off dynamic batching.
