[General] Problem with changing tile pathability

[Sigrun]

Hello! I'm back to modding after... well, many years out of the business. Many patches flew in after my departure and as far as I know latest ones broke extended editing tools. In the day I used them mainly for their ability to change tile pathability. How do I change it now in 1.30 vanilla editor? I simply want some tiles to be unwalkable and others to be buildable while now they are not.
