Most people forget that other programs (not just game engines) have tons of bugs. I do remember that 3dMax 2016 was crashing while working with CATrig so many times that it was not even funny. And it was like that in 2015 etc too.
I am not going to protect Epic by any means as child actors are main concept of my template and where I suffer the most, but I am at least happy that Staff of Epic comes by and checks the Bug Reports section of answerhub constantly. They even checked personally what’s wrong with my template by downloading it from me. That’s not something everyone does.
Anyhow, that’s my 2 cents.
