While it’s not a major bug I think if it’s possible to fix it could have the smallest effect on early game scouting fairness and finding your sheep (just pray that fixing it doesn’t break other things).
In the screenshot all of the brown tiles have sheep on them, and all of them are an equal distance from the Town Center (so it’s perfectly symmetrical).
NOTE: This doensn’t happen with any other building, only the Town Center.
Also for whatever reason it does not happen to Chinese Town Centers.
Thank you for the report and for the investigation! I’ve written this up for the team to take a look, and will let you know if they need any additional information about the issue.
