Buffs on friends buildings are incorrect.

Hi,
Today, after the last maintenance, I encountered a problem after placing buffs. I had 21 baskets in my star menu, and I went to a friends land to place 18 buffs, like he had asked me.
After placing them, I had only 2 baskets left, which means that I must have placed 19 buffs. Returning to my friends land, and counting the buffed buildings, I came to the amount of 18 buildings.
I did a refresh of the game, and so did my friend, but there was no change.
My friend had the same problem, he placed 18 baskets on my buildings, but after that, and even after the refreshing, there were only 16 buildings buffed.
I mention this problem, because it's hard to make baskets. There's allways a lot of fish, bread and sausages needed. The explorers need sausages too for seeking for adventures.
I hope someone will take a look at this problem.
