Objects disappearing at end of timeline, even though go til end
I keep getting this problem (I'm making my first storyline project). Everything will be working fine, and then I make edits to a part of slide and when I go to preview, the text, images, etc disappear from the slide right at the end. (I currently have a button set up to change from state of hidden to normal when timeline ends becuase I have audio). So, the Continue button shows, but things that used to also stay, now disappear.
When I go to the timeline, it looks like everything is all lined up at the end, so I dont know why the disappear -- I've had to just re-do entire slides - but maybe there is something going on that I'm not aware of. Any help you can offer would be greatly appreciated!
