I tried absolutely everything, hot reload doesn’t seem to work, I have to restart editor every time.

Here is log, it gives an error, but it doesn’t seem to describe much.

Here it is:

I tried to set Solution configuration to Debug Editor like in tutorial, I tried to compile UE4 from sources, still nothing. Any idea why? Thanks.

Okay, it’s the problem with constructor code changes, otherwise everything works just fine. Here is a topic on that: https://answers.unrealengine.com/questions/17816/hot-reloading-constructor-code.html
