Vlad Scenario below:
- Orion window with Profile 1 (Instance 1) open
- Orion window with Profile 2 (Instance 2) open
If Instance 1 crashes for any reason, a dialog box appears with a button to "Reopen" Orion. If reopened, the new instance will look like it's on Profile 1 (i.e. will show bookmarks, pinned tabs, etc. exclusive to Profile 1) but it will actually be using the cache/cookies of Profile 2. I verified this by opening Gmail and seeing which account was logged in.
To resolve this, I had to quit both instances of Orion (instance 2 and the newly reopened instance 1) then start a new instance of Profile 1 and open a new instance of Profile 2 from it.
For reference, Profile 2 in this scenario is my Synced profile, and Profile 1 is my Default profile.
I wish I could reproduce this further and help diagnose better but I don't know of any easy way to trigger a crash on demand.
