makes me wonder if it is an issue that is specific to SKA itself then -- I've created similar amounts of treasures at once via dockside (on auto yield) with no crashing
I play a deck that can reliably generate a large amount (10-30+ depending on the board state) Storm-Kiln Artist (SKA) triggers to create Treasures.
Two of the last 3 times I have played this deck and established a large board state, the game will crash ("Magic Online has encountered an error")...
