Huh, well that's a new one for sure – very sorry about that! Pretty sure how and why that happened to you based on the helpful screenshot: this is caused by a major known game-breaking bug that we're aware of and we’re about to release an essential fix to patch this, coming this weekend. Will test to see how this happened and fix it, thank you!
Edit: found the issue - this was caused by attempting to go through the Office Doors during Mission 15's dialogue - the player shouldn't have been able to move around during that to go through those, so now fixed both issues - thanks!
