They give you back stuff when you cancel a crafting, cancel a mfg or cancel the upg of a non-guest race building. So why can’t they give you a way to stop a scout and just take back anything they give you? And maybe be give back your coins?
Start a scout
Get KP
Spend KP
Stop scout
There is also the Tome of Secrets that gives you supplies when you start a scout. That goes back to about the launch of the game, so there has always been something that triggers when a scout begins that prevents the cancelling of a scouting. Oh, plus the slight increase in costs and difficulties of all unscouted provinces that happens as soon as you start a scout.
Thank you
