I have been working on a rather extensive VR experience. I copied the scenario to have a backup. As I have done it, I realized that all the variables in the Actions panel disappeared and now I have blank spaces in the whole experience (that's hundreds of times I used the variables!). It really stresses me out because I have not known of any issues or limitations, now I have a delivery of this project next week, and feel like my main problem now is the software not being reliable.
