Village trade values inaccurate

I can't seem to post them here, but I sent to your inbox. As it happened, right after this post, there was an offer in the village of 4800 silver for 3000 wood but only 3750 was delivered


Checked the images, looks like a bug but can also be cache problem, the numbers you see might be not updated... I have to check my self this kind of stuff, it is something we don't often see what come and goes...
