Maybe it dropped the frame rate a little? I l know in Unity if you have really thin colliders, and yours seem pretty thin, you can teleport through them if you move through them in less time than a frame so maybe by spamming it I dropped the frame rate low enough to get through. Don't know if that's a thing in Unreal. Tried the game with the door knowledge and it's nice, the lighting system you have is pretty fun though it's still pretty dark. I still think upping movement speed would be good but you made a nice town there and some interesting tidbits in the notes I found. You might put the thing about the doors in the game description so more people can at least get out of the building and look around. Good work with all those time constraints, what is there is attractive.
