Mario And Sonic At The Winter Olympic Games: Adventure Tours Mode

I dunno if anyone can help me but I have two spots I need help with.

1.) In the Polastraits I can't find my way to the fourth Snow Crystal Mission which is all I need to break the ice wall and battle the boss: I've done four of five missions: Big The Cat's Alpine Mission, The Luge Mission to recruit Yoshi, The Luge Mission by the Yellow Shy Guy and the Bobsleigh mission near the cannon. Can anyone tell me where the missing Mission is?

2.) In Frostown Tails can't repair the broken gate machine until he finds an identical one in Frostown. I searched the entire town and didn't find an identical machine. Can anyone tell me where it is?

If you can help thanks in advance and if not, thank you for trying.

 

you can find the machine in polastraights

take the cable car or whatever it's name is and you will find
the last mission.

 

The broken machine part, I think it can be found in Polastraits or Sparkleton.

I think you're missing the Wario & Waluigi mission.

I haven't played the game for a long time so, I tried.
