But the next time I start Ubuntu, the 12 dots are replaced with enough dots to cover the encrypted version (which has been encrypted correctly and stored in /etc/network/interfaces) - when I re-enter the clear-text (which is covered by dots), I'm connected again.

You should not use /etc/network/interfaces to store configuration
information when using NetworkManager. NM stores configuration in itself.
