Mana Usage Issues (Manual + Auto-Tapping)
Issues when trying to use mana in a certain way: playing a deck that involves snow lands, as well as Sanctum Weaver (creature that taps for X, where X is the number of enchantments you control). Cast Sublime Epiphany with one mode being to create a token Weaver. This would allow the original Weaver to tap for one extra mana as another enchantment (the new token Weaver) would be on the battlefield, so I'd prefer to use my lands to pay for the Epiphany.
The auto-tapper wants to tap the Weaver, as it can't tell that using the lands will result in one extra mana becoming available. It makes sense, and is a situation where manually mana spending would make sense.
HOWEVER, trying to spend the mana manually - I just can't. I tap the lands, then go to tap the mana symbols that are created - the way I recall always doing manually spending - and nothing. I suspect it has something to do with the coding of snow mana; nothing about any spells or permanents I had in play should have been restricting what the mana could be used for.
Please fix. Can literally lose games.
