Exception when editing code.

I wasn’t even doing much of noteworthy. I created a new file, as was manually moving some code around. If you have any more questions, I’d be happy to answer if I can.

I failed to reproduce this issue exactly, but parentByStub was definitely broken (#613). It is now fixed, so I hope this issue is also resolved. The fix is included in the latest nightly.

I’ll close this, but please reopen if you still see the issue after the update!
