Simulation doesn't work without lapse steps

[buster-blue]

In my current deck options setup, I don't have any lapse steps and instead just use a new lapse interval for failed review cards, but the simulator won't run if you don't add any lapse steps, along with"% correct lapse steps" as well.

Thanks for reporting! I wasn't aware that is was possible to have no lapse steps. I'll have a look at this for the next update if I can find the time to work on this project again, not any time soon I'm afraid
