AFX is acting very odd lately, and since one of my collagues had the same problem, this is clearly not an isolated issue.
Here's what happened:
I'm working with imported swf files (doing extensive cameramovement between layers, using rasterised formats is not an option). After a while, the program starts to show some errors.
The files that worked just fine a moment ago, crop themselves at weird places, start flickering during preview, or disappear altogether.
The layers, the files are still there, but they seem to be empty. Later on, I tried to open the source files with the normal SWF player, and they also became empty!
There is seemingly NOTHING in the file, which has been clearly working a moment ago!
What's going on?
Turn of the Write XMP ID To Files On Import preference.
I have seen cases in which that causes problems with SWF files.
