The step button (the button at the right of the "start simulation" button) has some bugs:
ConcurrentModificationException
Load a solution
Frequently press the step button multiplye times
Sometimes a ConcurrentModificationExceptions occurs in the workbench log and the currently loaded simulation can't play anymore.
Press after finished solution
Load a solution
Let it play until finished
Press the step button multiple times; at least twice (ideally, this should have no impact)
Try loading another solution or reloading the same solution
The solution won't load. Sometimes the ConcurrentModificationException mentioned above occurs and sometimes doesn't. If it doesn't occur, you can continue trying to load solutions which works sometimes. I think the number of times you have to try loading a solution depends on the number of times the step button has been pressed.
It can also happen that the new solution loads but can't be played.
