We've had a few reports of crashes-on-load in the update from a couple hours ago; they pointed to trouble in one of our debug visualisations (which are all disabled by default, but were being generated whether or not they were visible). In this build I've temporarily disabled those visuals while I figure out and fix the issue. Sorry for the inconvenience!
This change has no effect on the game except for temporarily removing one of the debug visualisation options while I figure out the underlying issue.
