This looks like an oversight and a bug.

If the rewards are per-server, they shouldn't have been named "account deeds".

If they are indeed per-server, transfering a character should not prevent from re-earning the deeds on a new server.
If it's impossible to earn account deeds at all (by any existing/new character) on a new server, that's an outright bug.
If it's impossible to earn account deeds by the transferred character, it's a huge player inconvenience, and is worth attending to.
