some base layer objects don't show after hiding layer
I have a slide that has 3 buttons on it. Each button opens a layer. Each layer has a 'close' button that hides the layer (via trigger). The base layer objects are hidden on the layers. The problem is that the 3 buttons on the base layer don't display when the layer closes. Example: Start on the base layer, which has 3 buttons. I click on button 1 to show layer 1. I click on 'close' to hide the layer. I'm return to the base layer but only button 1 is showing. This has worked in the past. Has anything changed with Storyline that I'm missing?
