My player pegs are so hard to incert into the busts I feel like I'm going to break either the pegs or the busts. Is there a any way to fix them?

If you look around (BGG and so on) this is a typical problem. They also say that after frequent use it gets better. My set is still quite new, so it's difficult as well.

BTW, I have 2 friends with the game and they have this problem too.

At first, I was also afraid of cracking the busts, but after 3-4 games the pegs tend to insert smoothly.

For us they didn't improve that much over time, some of the busts are just too tight, especially those that came with the original box, so i used a modeling knife to widen ever so slightly the holes inside the busts. Going slow and precise, it worked wonders and now they are all snug-fit and easy to remove.
