was this changed recently?

As to my knowledge, except for bugs and as TheBoot above said, nothing has changed for now.

However, due to the commented upon limited radius of the "no-spawn zone" around the workstations, try to see if you have any area that is uncovered. Worst case scenario, you might have to put down a workbench, campfire or similar somewhere.

Personally, I tend to go for the "honeycomb coverage" of the areas, using temporary small poles to know where the limits of the areas go and make them overlap slightly at the borders. Apart from the glitches from time to time, it seems to work.
