Bug / Crash Particle editor not working at all Unity 2018.4

[Ian_W]

I'm on unity 2018.4 and all the rope components seem to work, however, none of the inspector widgets seem to be working. Whenever I hit the edit particle button I get a couple of hundred errors about a null reference exception in the ObiParticleActorEditor script on lines 332 598 and 262. I can sort of click around and eventually find spots where I can add pins but things aren't quite working and it makes it nearly impossible to set up ropes.
