We've just recently upgraded to CC and I'm a new hire, so I had no previous actions saved - I made new ones in AI CC and I never made them in the Default Actions set. A separate set has no efffect. It happens randomly and on some steps in some actions, and not on the same steps in other actions. Examples are Set Color, had been "Fill Color R:0 G:0 B:0" upon relaunch becomes "R:0 G:0 B:0" and returns an error when running the action: "the object Set Color is not currently available" - but it's happening with many different steps, such as: Move, Layer, Set Color, Transform. Obviously a serious bug and has NOTHING to do with SETS or with PREVIOUS VERSIONS.
So, this is obviously a work-around and somewhat untested at this point, but we've seen success with the method I reported earlier.
1. Load AI as normal (on first load, basically)
2. Open the Actions Panel
3. Leave the "Default Actions" in place
- this does NOT mean simply leaving the file in places in the .../Presets/en_US/Actions folder
- the "Default Actions" .aia file is in place automatically, so long as nothing else has been changed
4. Load other sets, as needed (other .aia files)
- here, our action sets are well-established... they were re-saved for CC without much change from CS6
- they contain between 6 and 20 actions, per set
On re-starting AI or re-starting the computer and re-loading AI, everything that was loaded stays in place. The individual parts of actions continue to work and no steps are "lost".
I have tested this on 3 machines so far with some success. I have 5 "testers" working through this today, who will ultimately put the application and this work around thorugh its paces in a much more thorough manner. Within a week, I'll be able to report more definitively on the success of this work around.
