Self explanatory title, I've clipped some videos about the bug
https://streamable.com/1y9sn2 (At the Kullervo's arena, that's where my drifter died, after I typed unstuck because I was legit noclipping through the entire Orowyrm arena I got tped back there)

Essentially what happened is when the Orowyrm was brought to the portal and I started playing as my Warframe, the game thought I was still a dead drifter so it merged the drifter mechanics with the warframe mechanics and ended up not so great (I think so).
