Commit Description:
Fix issue with simulation. Previously, if there was more than one tick being advanced at once, it would overshoot how many ticks it covered. So if it was covering 5 ticks and each tick happens every 100 units, rather than recording that it had simulated through t= 500, it would increase the cumulative time for each tick, recording that it had simulated through t=2500. Add error message, too.
