Toy, for the hundredth time, my only relation to the LL is exactly the same as yours, that is being their customer. I've no access to their code, never had and have no idea how it works.
Yet, I fail to see a relation between such issues as for instance "Order confirmation email failures" and "L$ balance not updating automatically inworld". To my experience, these would be totally different subsystems. Even assuming they get the data from the same generic queue (I sincerely hope it's not the case), the balances update just fine on the dashboards so wouldn't be the queueing problem.
