Cost of wonders: a bug?

[numberoneone]

Does someone know why do wonders change their cost during the game? It seems happen when the glass is acquired, but sometimes I don’t find the reason. I made some screenshots when the cost is clearly wrong…

Can we see those screenshots?

Costs of wonder stages should never change during the game (but of course, what you need to pay can and does change as you acquire more resources/money - I assume that's not what you're referring to, but I find it hard to believe there's such a fundamental bug in a popular game that's been regularly-played here on BGA for many years, without seeing some evidence. Most likely you're misunderstanding something but I can't imagine what without seeing evidence of the alleged "bug".)

[EDIT: missed that this was the 7WD forum - I thought you were talking about "plain" 7 Wonders! . See the reply after mine for more intelligent commentary!]

It must be that your opponent got resources required for your Wonder and you don't produce of these, the price of a resource will go up. It's 2 coins + how many your opponent has.

Example with The Great Library 3 woods, 1 papyrus, 1 glass. You produce 1 wood, 1 papyrus, 1 glass. If your opponent produces no wood, the wonder would cost 4 coins. Now, your opponent builds a brown card producing 2 woods on it. The wonder will now cost 8 coins because you'll need to cover those 2 woods which will cost 2+2 each.

I still want to see these screenshots.

I think the post above me solved the issue, but now I'm just curious how badly they hurt you with the glass grab. Are we talking Mausoleum and Sphinx. In that case they got you good.

Screen shots are too heavy to attach

But anyway, if the fist increase because the opponent has resources I don’t have, it is not in the original rules.
Some cards which require 3 stones cost 10 bucks…how it could be?
Seriously something is wrong with maths there

for example by you having a stone and opponent 3, math seems fine ....
