Game working fine in xcode debug. Crashes on release (using testflight)

The Game hangs for a second and then crashes. The app crashes if I restart the level or the score is going to be showed. I build in xcode 6.0.1. Testing on ios 7.1.1.
The console output says:

libc++abi.dylib: terminating with uncaught exception of type std::out_of_range: map::at:  key not found

Here is piece of crash report:

Exception Type:  EXC_CRASH (SIGABRT)
Exception Codes: 0x0000000000000000, 0x0000000000000000

Hi. I’m having the same problem. Have you solved it?
