Thanks for tips. I always wonder what’s going on with breakpoints.

I use logs very often so i’m surprised that it’s not working. This is my error log from VS builder after copy RestartPlayer function from AGameMode class to AMyGamemode.

For Example this line

UE_LOG(LogGameMode, Verbose, TEXT("RestartPlayer %s"), (NewPlayer && NewPlayer->PlayerState) ? *NewPlayer->PlayerState->PlayerName : TEXT("Unknown"));

generates this error
