It doesnt tell you even if you have enough sketches for it or not. 

If you click to upgrade beyond 30 it will auto take the required sketches without revealling the cost, you'll only know the cost by checking your sketches before you click. If you do not have enough, only then will it tell you how much you are short like it does with other resources for agreements.

Of everything I have seen so far (and that's a lot already...), this is the most astonishing one. I mean, how can that possibly happen ?! :O

When upgrading your buildings, it displays the amount of sketches required as is ****** normal, how come they keep it secret for the agreements ??

Are they so ashamed of its price that they don't even want to show it ? Now, they probably should, though the answer is probably rather that they rely on heavy coiners and not-so-smart players to just go for it without looking at the price...

They just have no limits, do they ?

Lefeubleu,  I did the same as you, upgraded javeline/akanthos.  Wanted to see how it went, so least amount of sketches wasted if it was a bad move.  When I didnt see a sketches amount needed for lvl31 I thought maybe only sketches needed for lvl32 jav, so I Iooked at my sketches amount that I had then clicked to upgrade, only then after click it warned me the amount I was short.  Now I knew how much it cost, so I bought some sketches and clicked again, It correctly took the sketches from my total. Again for final level, the cost is not shown beforehand.

Thank you for this report. Our developers are aware of this issue and they are currently working on it.

As soon as they prepare a fix, it will be released. Please be patient, it may take some time. Thank you for understanding.
