Is Unreal Engine for game developers or for engine troubleshoothers?

I’ve had one crash with 4.13 and three or four with 4.14 in nearly two months of working. Not complaining!

Deleting or adding blueprint nodes can crash engine - those are no good behaviours of production engine.

Not to talk about the crashes when you just try to open a Blueprint.

The only way I crash the editor is when sometimes I’m editing a FString property member of a TArray in details panel… If I press Enter then boom! crash (not always) though.
Never fixed so to avoid I will simply never press enter on any details panel input field ever again o.O
