Mirage teleport lands you inside building just to the southwest of friendly green walker.

I've had this occur a three times when attempting to teleport to my right side walker, I'll get stuck inside the building to the southwest of it. Video included to demonstrate. In real games the bug typically occurs when teleporting from base, so I don't believe proximity has any impact.

Notably (not included in the video, sorry.), unstick will not unstick you. It fails to move you at all.

To add, since I cut the recording a little short, the game will sometimes bring you back up inside the building when you fall. Falling towards the north wall has given me best results to escape.
