And it was...low! 2/3 gallon. Which now brings up a new problem.

If you haven't been checking it regularly, it may not be a problem.
Just monitor it regularly and see if it keeps dropping. Over time the
coolant evaporates and there is a tipping point where it can get low
enough to not flow into the heater core fully. You may have been
loosing coolant all along and the tipping point just finally was hit.
