I'm playing on v1.1-1226.
I'm on Year 1 Spring 12. Caught a Firefly, and before the Firefly information placard popped up I opened my menu because I knew that I didn't have room in my inventory. I grabbed an item, specifically wood, and the Firefly placard popped up again. Tried to discard my Wood in the trash, but the Firefly placard refreshed and I couldn't do anything. I couldn't place my item back in my backpack or trash it as the placard kept refreshing. Couldn't close the menu either, so I was locked and had to end the game via Task Manager.
