Barren’t redux - resource too far away

[reef edge]

The Roadworks Office is showing planks being too far away when the sawmill is just a few squares away, across flat land

Never mind, sorry, this has self-resolved (I should have noticed it switched to the stone by my screenshot!) and begun construction

I had this issue too. I just restarted my game and built the sawmil super close

Yeah i think you can get a warning for a couple of seconds and then it should update
