Lake Doric Not Keeping 100% Completion
I can confirm, this happened to me as well. I had 100% on the map, then when reset hit it suddenly went to 4/6 hearts and the percentage dropped accordingly.
Check the dev tracker for details, but short version: known issue, you will need to do those hearts one more time after reset and it should be fixed.
As SlippyCheeze said: the devs fixed a bug and the fix (unfortunately) reset the map’s completion status for those who had completed the two southern-most hearts. Once you complete them again (e.g. today after reset), all will be well.
