Freezing after landfall

Reaganstorme

This time the game froze after the opponent landfalled

My board: Nissa 47 Life
Greenwarden of Murasa 8/6
Birthing Hulk 5/4
Eldrazi Scion 3/3
Support gems: From Beyond (6), Nissa's Pilgrimage (3)

Opponent: Chandra 22 Life
Akoum Hellkite 9/8 Berserker Trample
Support Gem: Strider Harness (2)

The oponent made a non-red match-4 landfall and wiped one shield from my Nissa's Pilgrimage (now shows 2). The landfall triggered Akoum Hellkite's "deal 4 damage to a creature". They destroyed my Eldrazi scions which were removed from the battlefield. Neither of us accumulated any mana from this move.

Seems like the bug is in the mana resolution step in this instance.

Hope this info helps.
