Turn 15
Leonian Vanguard was triggered.
[My planeswalker]: Gain Life: 14
Dragon's Hoard was triggered
Divine Visitation was destroyed
House Dimir was triggered
Rupture Spire was triggered
Chord of Calling was cast by [My planeswalker]
Something was destroyed (from the House Dimir effect...?)
March of the Multitudes was cast by [My planeswalker]
Shalai, Voice of Plenty was cast by [My planeswalker] (From Chord of Calling)
Again, the bug is that when I cast March of the Multitudes this turn, Leonian Vanguard would show the animation for being reinforced, but the reinforcement stack would disappear as though it were consumed by Divine Visitation, which was destroyed before March of the Multitudes was cast. No angels were created, and the "-1" part of the animation when Divine Visitation destroys a token did not appear either.
This is not the first unpredictable bug that I have seen happen in conjunction with the massive lag caused by Chord of Calling. I'm not saying that's the culprit, but I have seen Infernal Reckoning trigger on nothing when disabled (a bug that was supposed to be fixed with this latest patch) while Chord of Calling had stored mana, while it acts completely as intended when Chord of Calling is not in hand/has no stored mana.
