Hi,
did you updated Unity ( for example going from 4 to 5?) or did you updated PlayMaker between the time the actions where there and when they disappeared?
Are you using the actions distributed by EasySave directly or the one from the Ecosystem ( arrayMaker likely)
and no unfortunatly, the parameters from missing actions are not accessible. you need to recoved the missing actions for the parameters to come back.
Do you have a back up? If you do we can analyze it and see why it's going missing.
Bye,
Jean
