Vaults that were removed in their original location continue to appear in Cryptomatir 1.5.6.
Schedule of events:
I Deleted an encrypted vault (“Vault X” ) in Finder (location was on iCloud in my case).
Opening Cryptomator 1.5.6.
Vault X appears on list of vaults (not a surprise)
Selecting vault and right mouse click (should enable to remove vault): doesnt exist. No way to remove vault.
(I temorarily fixed the issue with a Workaround: opened the file Library ▸ Application Support ▸ Cryptomator ▸ settings.json with Brackets (App).
Removed the location of the earlier vault, save file settings.json
Then restarting machine / osx. Old entry disappeared in list of vaults.
