I’m just forging around in the new map Waterfall in the current flight. Next to a create on the ice cave side where you can see the landing pad where the three hornets and the one pelican land in the distance. The crate near the man cannon by the corner, next to that crate is some sort of invisible one way shield or barrier that only affects the player when they are in the Ghost or Mongoose. Driving towards the corner, you hit an invisible barrier. However you go behind that barrier by driving around the crate and drive towards where that invisible barrier you get pushed towards the man cannon.
Hey OP, any feedback for the current flight can be dropped into the flight feedback thread: https://www.halowaypoint.com/en-us/forums/243780d3b80b4bb6ac7917a8942286db/topics/mcc-flight-%e2%80%93-february-march-2021/3880a430-ae93-4f5d-862f-42d6093e0889/posts
