shrines and gateways discovered again after reloading
After you reload, you get a notification when your units are near enemy or neutral shrines and gateways that you already discovered.

I believe this is due to the fact that the discovered state of non-owned shrines are not serialised when saving. However this is extremely extremely minor so I'll ask the code team if there's any likelihood of a fix to this issue or not before we pass it through.
