There seems to be a bug in this scene because it's possible to make Roger walk on the walls.

I'm using Windows 10 and ScummVM version 2.1.2

Thank you for the report, this is a duplicate of #9749. It's a ScummVM pathfinding bug in this room, and it's a tricky one.

I'm re-opening this ticket as it is different than #9749, although both pathfinding issues are in the same room. The other one was more severe and has now been fixed.

I've tried to work around this incompatibility with our pathfinding algorithm several times, but I haven't found an adjustment that works. Also it would have to be applied to two similar but different polygons: guardsAlive and guardsDead. This one will probably only be fixed by implementing Sierra's algorithm, although I think I've been able to walk out-of-bounds in this room in the original too. But that was a long time ago so I might be remembering that wrong.

This out-of-bounds bug does not break the game, it just lets you walk up and down the walls.
