[2022] Skullduggery V :Building the Boom

Anyone found the rest of the explosive components? (il try to update myself too)
Ramsgate : The island behind Gregario Flynt
Conundrum Rocks: As soon as you arrive take the vent that leads to the upper islands
Iron Falls: After arriving, head right to vent across a gap, then 3 quick vents going up. It'll be to the right behind a tree. Very top right part of the map by the uppermost waterfalls. (Credit to u/No-Station-7421)
Frostmarch: This one is tricky to describe but I'll try. After spawning, take the Aether Jet and after you land you should hear Stalkers (i.e. Boreus Minions) screech. Ignore them and take the next Aether Jet at the top of this hill. Fly over the smaller platform and glide a bit to the right where you see a big cluster of trees and red bushes on a hill at the edge of the island. The Cache is at the top of that hill. If you don't see the Cache, you missed it because there's another smaller hill (closer to the ground) with trees next to this one. (Credit to u/Charetta)

Restless Sands: After spawning, immediately follow the right path. Keep "hugging" the edge of the island if you want. Take the Aether Jet upwards to higher platform, run straight ahead past a few Phoenix Opal and some trees (alive and dead ones), drop down and turn around. The Cache sits by the cliff wall. Maybe a couple of Gruk-Gruks will spawn nearby. (Credit to u/Charetta)

Edit:Thanks everyone we found them :)
