[stem-dev] Out of range error when using triggers

Hi all,

I was wondering if anyone knew what might be causing the error below when I run my scenario "Jan19"?

When removing the triggers generated by my pajek graph, the scenario runs normally. However, when the triggers are included in the scenario, progress on the simulation control remains at 0% for a while and then this error appears. 

An internal error occurred during "Jan19"
org.apache.commons.math3.exception.OutOfRangeException: -0.045 out of [0, 1] range
at org.apache.commons.math3.distribution.BinomialDistribution.<init>(
at org.eclipse.stem.core.math.BinomialDistributionUtil.fastPickFromBinomialDist(
at org.eclipse.stem.solvers.stochastic.impl.StandardStochasticImpl.step(
at org.eclipse.stem.core.scenario.impl.ScenarioImpl.step(

I've had a go at troubleshooting this for a while and have run out of ideas of what to try next to get it to work. 

If anyone has any ideas of what the issue might be, then please let me know and I will try to investigate further! 

Best wishes,
