Crash on Safari on macOS

[NerdyTherapist]

For whatever reason, the site consistently crashes on Safari for me. As in: Safari becomes completely unresponsive and has to be quit manually.

macOS 10.12.2 (16C67) on iMac13,2
Safari 10.0.2 (12602.3.12.0.1)

Let me know what I can do to help figure out the reason for the crash or what other data you might need.

That's not very good, thanks for logging (and thanks for the versions).

Does it crash immediately or after some expanding/scoring?

Is dev tools open by any chance?

The site starts to load but then hangs and Safari beachballs. I've attached a screenshot with the developer tools open. It clearly shows a very long network request. I've also attached a stacktrace after quitting Safari. Can you find out if this might be a bug on Apple's end, so I can file a bug report with them?

(I've just yesterday updated to the latest versions of macOS and Safari.)
