I have a problem trying to place walls in 2.45.01.
For one thing, pressing the buttons on the wall window changes the language to, I believe, french.
More critically, the walls immediately collapse into dust when the simulation unpauses after placing them. Also, I've had a bot able to cut through walls nearly effortless ly.
Any workarounds for these?
EDIT: That's actually 2.1 I have right now.
