[2025 Day 1 (Part 2)] [C++] Where have I gone wrong?

I have never struggled with a Day1 like this before, so I'm a little embarrassed to have to ask for help. Here is the code I have tried:

Part2

The definition of a 'Turn' is: class Turn { public: int clicks; Direction dir; Turn(char d, int c) { switch (d) { case 'L': dir = Direction::Left; break; case 'R': dir = Direction::Right; break; } clicks = c; } }; My solution for Part1 worked so I am reasonably confident the input is parsed correctly, and my part2 solution (pasted above) works on the example provided. Where have I gone wrong?
