Hello, I may have made a little mistake... In the excitation of the new prefab workflow and the gain in productivity it brings (and it does, this is awesome!), I started my new project with the beta version of Unity including the new prefab workflow. However, after integrating my ad mediation service, I encountered a crash in my game, which, I believe, is not related at all to the ad mediation service but more to this beta version. Here is the full crash stacktrace: I have no idea what can produce this crash or is there is a way to fix or at least to work around it. Therefore, I wonder if there is a way to downgrade my project to the latest 2018.2.1 official release through some rough modifications in the prefabs files of my project. Thanks for your help. I can provide any kind of information related to this topic if necessary.
