So uh, after getting a good portion of the level done -- I went to both calendar puzzles, solved the second and whatnot. I've run into a snag. I had this happen before when I went to the second calendar puzzle as well, because I went the wrong way. But in the fork in the road when you leave the second calendar puzzle and turn right, immediately after one of the gates and right before a tunnel it looks like, Lara freezes and the bike keeps going a bit ahead. She'll be in the riding position but in midair and unable to do anything except reload. I've tried a few things but have not tried restarting the level yet. I haven't seen a thread for this yet, so if it was posted sorry and thanks for your help~
