base slide objects vanished
recently finishing up a system simulation project and I was doing a last run through before publishing.
In one section I discovered that all the slides that had layers in had mysteriously decided to not show any of the base layer objects!!!!
I've checked all the little eye settings, and the cog wheel settings on the layers and everything else I can think of, I've even compared like for like on each slide with a section that has the same type of things but works fine?
