fuzz testing errors - uncaught assertion and undefined property #49

Closed jbphet closed 8 years ago

jbphet commented 9 years ago

I just ran the test-server, and Atomic Interactions is failing the fuzz test. Looks like there are two separate errors:

I just set this up for fuzz testing for a while, and so far (about an hour), I'm unable to duplicate. I also ran the test-server a few times, and the automated testing of this sim passed each time. I know ArrowShape was undergoing some changes, so maybe at least one of these was caused by a temporary situation.
