Hi.  
I have to compile the C++ code for 3-4 times before playing the game to avoid the game from crashing because of an inner problem in the Multicast Delegate and Delegate classes.

```
**Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0xffffffffffffffff

I know my code doesn’t have any problems and I think that Hot-Reloaded objects replace the main object and the multicast delegates get to point to a null delegate. Any opinions on this?
