castle rebuilding

[thinktank]

So I built my castle to level 5. Then I clicked build castle again for level 6. Before level 6 was complete, my level 5 castle got destroyed. Let's say enough time has passed for the level 6 castle to be finished. To repair, I need just 1/5 level 5 castle stone requirement, right? Or do I need 1/5 stone of a level 6 castle?


If I subscribed, then from the site: "An automatic start of exploitation for buildings and researches". Does the castle automatically get started at level 6?

But if I didn't subscribe, then I couldn't have clicked on the "Start Exploitation" button. So that will still be level 5  stone requirement, right?

if fort 6 isn't activated, then it is still fort 5 and you'll pay 1/5 stone of fort 5
