HI,
Thanks for getting in touch, sorry to hear about these issues. I can reproduce the crash here, and I'll pass it over to our development team for further investigation. You can get around it by converting the RailClone object to native instances using RailClone tools, although there are a lot of objects so it slows down performance a bit. In my tests the issue seemed to affect only IR mode. Was that also the case for you?
Best,
Paul
