During the Dragon Wars, I had 3 creatures on the battlefield. Memorial to Glory was popped and the summon soldier token box populated. Either selecting ''not now" or selecting a creature for the token to replace did nothing, freezing the game. A ticket was submitted.

It seems to be any attempt to replace something with a token.
I had a creatureless Tezz2 deck with Rite of Belzenock, Thopter Spy Network and his 2nd ability, any combination of replacing one with another freezes things.
Same here. Cost me 12 points.
Also, one of my team mates had this occur on the AI’s turn, the soldier token picture turned up and since the AI can’t replace creatures the token picture just stayed on screen and the game did not resume.
