[0.17.4][mac] Crash with specific save

[lobf]

Hi there-

I'm playing the (current) latest beta on OSX Mojave 10.14.2, and I'm getting a consistent crash after a couple of minutes on the attached save. All I seem to have to do is let things run for a minute and it crashes.

My log file is here: https://hastebin.com/fayimipazi.coffeescript

Hope I did this right, thanks for any help you can possibly provide!
