Can't send customer email without account creation
I've just been trying out Kickstart 2 for a week or so - first I installed it with the demo store to explore it, now have wiped and reinstalled without the demo content. The only additional module I've added is SagePay Form Integration (dev version) and this seems to work fine.
My problem is with account creation in the checkout process. I don't want this, so I disabled the "Create a new account for an anonymous order" checkout rule, as I read in the docs here (if I understood correctly) that this is what to do. (I also disabled "Assign an anonymous order to a pre-existing user").
However when I do this, although the account is not being created, which is what I want, it also stops not only the "An administrator has created an account..." email (good), but also the order completion email (bad - this needs to be sent).
Can anyone advise what I'm doing wrong? Thanks in advance.
