Wiered errors when changing versions in Unreal engine 4

I got a wired crash error due to a specific actor on my scene when extends from an actor. The error didn’t happen in 4.2 it happened after I updated to the new engine.

I nearly checked every function of it which might have been responsible to cause the error and found none.

I just to recheck, created another actor and coped all functions and variables from the first actor which was responsible for casing the crash.
And then the 2nd actor works perfectly.

This kind of error has happened to me twice. I wonder what might be its reason.

Could you provide the error message that you are getting so we can see if it is a problem one of the many developers have experienced before and know how to solve?

The editor just hangs. Even while simulating. I did the exact same thing on the 2nd actor, it didn’t cause any problem.

This same error has happened to me before but with another actor.

Well I created an actor having a few variables, a few functions and a static mesh component. I assign the value to that static mesh component by making an actor of the blueprint. Normally when i place the blueprint in the level, the editor doesn’t crash but when the blueprint simulates physics, it crashes(gets stuck). Then I need to open the task manager and close it.

Just to recheck it I created another actor in c++ having the exact same variables and functions as the last actor. And assigned it a mesh in blueprints in the exact same way. But this one works fine when simulating physics.

The error is solved but, I want to know if something like this has happened to anyone before and how did they got over it?

That is strange, I would like to know what caused that as well just in case I run into a similar situation. You try cleaning your build and rebuilding? I am wondering if its a corrupted compile of that actor. Just one of my guesses as to what could of caused it.
