I was having issues with System.TimeSpan variables becoming undefined/unusable inside arrays due to Odin not recognising them even though it’s a valid C# class and work perfectly inside the editor.
After adding System.TimeSpan to the AOT Generation list my build worked again and I can now see the actual data being displayed properly.
I am using unity 2018.4.14f1 and Odin 220.127.116.11. The build was for iOS so on a Mac Platform, tested on both Unity Cloud Build and my local Macbook Pro. Editor Only Mode is turned off.
