I started a fully blank C++ project. It occured with the first hot reload. Strangely, it didn’t occur in the next 2 hot reloads. But as I have noted before, in our main project on 4.13, it occurs almost every time, but every time it occurs for different objects. And every now and then we get that internal crash and component data on some of the instances gets reset, but not to defaults we specified in our constructor, instead the defaults of the component’s own constructor. Then UE4 saves these modifications, which makes hotreload very dangerous for us to use.
