Probably already out there, but adding more to it.

Steps to reproduce: Have Ashaya, Soul of the Wild on the board and play Mythweaver Poq

Platform: PC

Result: A duplicate Poq is spawned, triggering landfall effects including its own (not the original one's because it's a "once" trigger) one before being evicted as a Legendary duplicate. And it goes on forever since it's not a "may" effect, even after both players' decision timers run out; and my game crashed, don't know about the opponents'.

Expected result: Game drawn.

Workaround: Detect it and draw the game? Since it's a two-card combo it shouldn't be that hard to detect.
