I only started playing recently
When I read forums, I occasionally see people claiming that building quarries next to farms is simply a good idea, or that it increases quarry output
Since July, I have tried every combination of level x quarries next to level x farms, on the same level and above and below each other. I have not noticed different stone mining amounts in the building description or in the pickups. I haven't recorded the time between pickups, but the building description doesn't change and when I take the pickup it shows the same time remaining as ever.
Does this adjacency buff still exist? Or was it patched out?
