Autotap taps more than necessary

If you have a source producing 2+ mana such as Sol Ring or Ancient Tomb, it often gets used presumably for the last remaining 1 mana to cover the cost. Example: you have a forest, a Thought Vessel and a Sol Ring in play. Cast a spell for 2G and autotap often (if not always) taps forest, Vessel and Sol Ring when just forest and sol ring would have been enough. Probably a problem with prioritizing.
