Thanks @lazarljubenovic! I have been taking a bit of a break from working on ts-morph, but I will get back to it very soon. I’ll probably do a quick release to fix this bug over the weekend though.

I’ve gotta hijack this to tell you that I love how you explain the bug when you understand it, @dsherret! Keep up the great work maintaining the lib 😃
