Attaching groups of blinks together sometimes crashes the simulator

This one is hard to reproduce, but it has effectively prevented us from using the simulator for playtesting mechanics. If we can find more specific reproduction values I'll update this issue. Playing around with connection and disconnection will trigger this bug within a few minutes.

I'm aware of this, haven't been able to capture it, let me know if you find out the path to reproduce it. Thanks.
