I'm in A20 and I placed a land claim block. I accidently hit it with a hammer but was able to repair it to 100%. I wanted to activate the visible border lines and I can't interact with it. I press my default key of "E" and nothing happens. It shows the land claim block at 100%. I even went as far as destroying to place another. Same thing. I included a screenshot of what I see when I hover over the land claim block. I went as far as even removing the 4 mods I was running and restarting the game then loading up my saved game. Same thing.
I loaded up an earlier game I started with A20 using the "Navezgane" map and that seemed to work okay. I was able to interact with the land claim block. So it may be my randomly generated world that's giving me problems.
I will try to create another randomly created world to see if continues but wanted to throw this bug report out there.
