In one turn, I cast:
Jhessian Thief
Rage of Winter
Eternal Isolation
Veil of Summer
Last entry in the Battle log was ‘Veil of Summer was triggered’, and then the game hung with the Spinning wheel of death on the screen.
Sounds like this issue: https://forums.505go.com/discussion/80877/bug-tdw-investigating#latest
veil of summer is one of the many cards that will crash the game when you’re holding a flip card (in this case, the queen of ice returned to your hand after you played rage of winter)
sounds like they’re working on a fix for this, hopefully that comes out real soon…
