My question is not important but i was just curious. I had a castle which was big in size and i liked it but then when i sent some of my units to my outpost the castle went smaller. I was just wondering what does size mean and how can i get it back to the big size i had before.

Basically in the link the bottom one was the one i had and then after sending units i got the top picture size.

The size of your castle depends on the amount of workers you have. The more workers, the larger the castle.

You can check here for the exact amounts of workers

Your castle size depends on how many workers you have, if you have 800 workers u have huge castle, if you have 600-799 workers you castle is big, 400-599 is medium castle, 200-399 is small castle 0-199 workers is TINY castle

Exactly, and looking at the spy protection, they seem to be at different ticks, meaning you waited, than got workers

That or you just added spy protection lol

Also, if you are making troops and you decide to hurry them it will cost extra workers with the amount depending on type.
