Found a bug. On level 2 of Hailey's mission, I can no longer use the key to open the door
Update: it seems all items that interact with environment are bugged. I can no longer use dynamite to blow up boulders now. I tested other keys on different levels and I cant open those doors either.
Also I cant open the shop on Hailey levels now. I can on Annie levels though.
Update: Restarting the game seemed to have fixed it. Not sure what happened.
