It was my understanding that any building that required workers are the only ones requiring a "space" to allow access. But most versions before 1.3.0 would allow non-employee-required buildings to be build next to each other without "space". This issue I'm having just started with v1.3.0.
No, before was all building, not just the building using worker.
Repeat, prob was a bug fix.. :P
Gewisse, try going to each of the deactivated buildings and manually activate them, it should make them work again.
HERE is what causes that IF you click on a solar tower that is surrounded by other towers it deactivates it
never click on them and they will be fine . here is simple fix deactivate a tower on the out side touching ground or road then click stats on that tower then click activate ALL
