Hi,
i just tried this again and now it does not happen to me neither.
But i noticed that strange things start to happen when i am working for a while in a project.
for example changing variables on an action and when played they are not changed,
I need to change them and look to another object and then it works and some different strange stuff...
When i restart unity the problems usually go away again.
i am using windows 8.1 64bits btw
