Couple of bugs

[Legather]

In the 'Come at the King' side mission where you see who's organising the attacks on Harlem, only the villain's head is visible so it looks like it's floating without a body. After turning in the mission and getting the Winter suit, returning to the 2020 suit and most of Miles' body is invisible, just things like shoulder pads and shoes are visible but uncoloured. Reloading fixed the latter glitch.
In the Greenwich Underground Hideout, there's a patch of the floor under the scaffold you pull down to reach the tech cache that seems to show under the world.

When running up or down steps in the Oscorp marine science section, Miles T-poses. He does a sort of penguin waddle up the slope after the dive suit exhibit, his arms lift up as if he's going to t pose from walking but don't make it far and stay semi outstretched.

EDIT: Just played through on NG+, didn't get the floating head bug nor did I get the t-pose issue in the Science Centre. I played in a different suit (ie not the 2020 suit) and only did occasional side missions, not sure if either of those are the culprits.
