I don’t know what you use to write your code, but if you use something like VisualStudio, Processing or Python, I’ve never experienced a crash that forced me to restart the corresponding editor or even the entire machine.
What I actually get is feedback. Something like “there is a problem [specification] in line xy”; if UE crashes because of an error, that is a problem with UE that has long since been solved in other software. In UE there is no hint, no feedback, nothing that could serve as a starting point for any troubleshooting.
And I don’t code here - I use BluePrints. If these BluePrints are not able to generate working code, that’s a bug too, not a cool feature. If those Blueprints are not returning any indication of a problem, this is a ■■■■■■■ bug.
Now we export that as game.exe - again, no feedback, no hint, nothing that would help you identify the problem. Nothing to indicate that something that works in the editor still couldn’t be exported because of [meaningful information].
And you say “editor tries to make it easier to develop”. Sorry, but that’s just stupid.
