Hello!
I'm having a weird little problem here. I have a project that started out life as a Unity4 project, but which I've since brought into Unity5. After doing so I updated Playmaker and am now at 1.7.8.3. Playmaker has been apparently running fine, and I don't have any errors.
The problem: Not sure how frequently, but sometimes when I make changes in the Playmaker editor and then hit play, the changes are lost. You can see it happen in this screen capture:
http://screencast.com/t/MeWyBwUmxxryThere I'm going through and removing the word "Canvas" from the Set property names. I edit three of the names and hit play. As soon as the project runs the words Canvas reappear - the changes are lost.
I found mention of something like this here:
http://hutonggames.com/playmakerforum/index.php?topic=1974.msg8653#msg8653But the solution there was to update Playmaker. From what I can tell, I'm currently up-to-date.
Perhaps coincidentally, this state machine was giving me trouble with some Set Properties I've since deleted. These were set to change the Text component of a 3D Text object. It was having so much trouble I tried the new UI > Text in world space instead. That seemed to work better, but then I realized as I continued to work that I was fixing things I could have sworn I had already fixed.
It started happening so consistently I caught it in that screen capture.
Another thing I wonder about: This state machine came into this new version as a prefab. Then I decided I'd rather work on a scene object instead of on the prefab, and broke the connection and deleted the prefab.
So maybe a few opportunities for mayhem to work its way in there. But it's been so solid overall that I don't feel like I'm seeing anything mentioned in the Unity5 troubleshooting guide.
Any help or suggestions would be greatly appreciated!
