'Next' button not activating on branched slides
I have branching slides in my course that are two slides (information and a scenario). They are numbered slides 3 - 10. I've noticed in previews that sometimes the 'next' button activates at the end of the scenario slide timeline and sometimes it doesn't. If it doesn't, I click preview and go through the information and scenario slide a second time and then it appears. It should always appear whether the scenario answer is correct or incorrect. I haven't been able to identify a reason.
